GREEN-EMITTING PHOSPHORS AND DEVICES THEREOF CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application is a non-provisional application and claims priority to U.S. Provisional Patent Application Serial No. 63/009,800 filed April 14, 2020 for “GREEN-EMITTING PHOSPHORS AND DEVICES THEREOF”; and to U.S. Provisional Patent Application Serial No. 63/073,391 filed September 1, 2020 for “GREEN-EMITTING PHOSPHORS AND DEVICES THEREOF”, each of which is hereby incorporated by reference in its entirety. BACKGROUND [0002] The subject matter described herein relates generally to phosphors and devices, and more particularly, to green-emitting phosphors. [0003] Current display device technology relies on liquid crystal displays (LCDs), which is one of the most widely used flat panel displays for industrial and residential applications. However, next-generation devices will have low energy consumption, compact size, and high brightness, requiring improved color gamut. [0004] LED packages for use in displays are based on a combination of a blue LED, a green phosphor and a red phosphor. The color gamut is largely determined by the choice of phosphors. Red phosphor K ₂ SiF ₆ :Mn ⁴⁺ has a peak characterized by a full width at half maximum (FWHM) of 6 to 8 nm and yields high color reproducibility in correspondence with the relative intensity of the emission peak. Green phosphor, β-SiAlON: Eu ^{2 +} has a full width at half maximum of 46 to 52 nm and has a peak wavelength of 534 to 540 nm, which is not a pure green but rather is greenish yellow in color. Accordingly, there is also a need for new green- emitting phosphors that efficiently absorb blue radiation, provide high quantum efficiency, and have improved color rendering.

As such, the drawings are not meant to include all conventional features known by those of ordinary skill in the art to be required for the practice of the embodiments disclosed herein. DETAILED DESCRIPTION [0036] In the following specification and the claims, reference will be made to a number of terms, which shall be defined to have the following meanings. [0037] The singular forms “a”, “an”, and “the” include plural references unless the context clearly dictates otherwise. [0038] Approximating language, as used herein throughout the specification and claims, may be applied to modify any quantitative representation that could permissibly vary without resulting in a change in the basic function to which it is related. Accordingly, a value modified by a term or terms, such as “about,” “substantially,” and “approximately,” are not to be limited to the precise value specified. In at least some instances, the approximating language may correspond to the precision of an instrument for measuring the value. Here and throughout the specification and claims, range limitations may be combined and/or interchanged, such ranges are identified and include all the sub-ranges contained therein unless context or language indicates otherwise. All references are incorporated herein by reference. [0039] Square brackets in the formulas indicate that at least one of the elements within the brackets is present in the phosphor material, and any combination of two or more thereof may be present, as limited by the stoichiometry of the composition. For example, the formula [Ca,Sr,Ba] ₃ MgSi ₂ O ₈ :Eu ²⁺ ,Mn ²⁺ encompasses at least one of Ca, Sr or Ba or any combination of two or more of Ca, Sr or Ba. Examples include Ca ₃ MgSi ₂ O ₈ :Eu ²⁺ ,Mn ²⁺ ; Sr ₃ MgSi ₂ O ₈ :Eu ²⁺ ,Mn ²⁺ ; or Ba ₃ MgSi ₂ O ₈ :Eu ²⁺ ,Mn ²⁺ . Formula with an activator after a colon “:” indicates that the phosphor composition is doped with the activator. Formula showing more than one activator separated by a “,” after a colon “:” indicates that the phosphor composition is doped with either activator or both activators. For example, the formula [Ca,Sr,Ba] ₃ MgSi ₂ O ₈ :Eu ²⁺ ,Mn ²⁺ encompasses [Ca,Sr,Ba]3MgSi2O8:Eu ²⁺ , [Ca,Sr,Ba]3MgSi2O8:Mn ²⁺ or [Ca,Sr,Ba]3MgSi2O8:Eu ²⁺ and Mn ²⁺ . [0040] The green-emitting phosphors of the present disclosure absorb radiation in the near-UV or blue region (a wavelength range between about 400 nm and 470 nm) and emit in a narrow band with a main emission peak centered at a wavelength range between 500 nm and 550 nm, particularly from about 510 nm to about 530 nm, and more particularly from about 515 nm to about 525 nm. These phosphors are useful in display applications. Gamut of a display incorporating the narrow band green-emitting phosphors, which may be measured according to NTSC, DCI-P3, Adobe, or BT2020 standards, may be significantly improved relative to phosphors that have a relatively wide- band emission. [0041] In some embodiments, the phosphors contain phosphate/vanadate groups, and are of formula [Ba1-a-bSraCab]x[Mg,Zn]y(UO2)z([P,V)]O4)2(x+y+z)/3, where 0≤a≤1, 0≤b≤1, 0.75≤x≤1.25, 0.75≤y≤1.25, 0.75≤z≤1.25. In some embodiments, one or more additional activator ions may be present, such as Mn ²⁺ , Mn ⁴⁺ , Ce ³⁺ , Cr ³⁺ , Eu ²⁺ or Eu ³⁺ . In particular, the phosphors contain phosphate groups, and are of formula [Bax[Mg,Zn]y(UO2)z[PO4]2(x+y+z)/3. Particular examples include Ba[Mg, Zn]UO2(PO4)2, and more particularly BaMgUO2(PO4)2 and BaZnUO2(PO4)2. [0042] In other embodiments, the phosphors contain [P,V] ₂ O ₇ groups in addition to phosphate/vanadate groups, and are of formula [Ba,Sr,Ca,Mg,Zn] _p (UO ₂ ) _q [P,V] _r O _(2p+2q+5r)/2 , where 2.5≤p≤3.5, 1.75≤q≤2.25, 3.5≤r≤4.5. In some embodiments, one or more additional activator ions may be present, such as Mn ²⁺ , Mn ⁴⁺ , Ce ³⁺ , Cr ³⁺ , Eu ²⁺ or Eu ³⁺ . In particular, the phosphors contain phosphate and pyrophosphate groups, and are of formula Bap(UO2)qPrO(2p+2q+5r)/2. Particular examples include Ba ₃ (PO ₄ ) ₂ (UO ₂ ) ₂ P ₂ O ₇ and gamma-Ba ₂ UO ₂ (PO ₄ ) ₂ (γ-Ba ₂ UO ₂ (PO ₄ ) ₂ ). [0043] In one embodiment, the phosphors may be Ba ₂ Sr(PO ₄ ) ₂ (UO ₂ ) ₂ P ₂ O ₇ , BaMgUO ₂ (PO ₄ ) ₂ , BaZnUO ₂ (PO ₄ ) ₂ , Ba ₃ (PO ₄ ) ₂ (UO ₂ ) ₂ P ₂ O ₇ , gamma-Ba2UO2(PO4)2, BaSr2(PO4)2(UO2)2P2O7, Sr3(PO4)2(UO2)2P2O7, Ca ₃ (PO ₄ ) ₂ (UO ₂ ) ₂ P ₂ O ₇ , BaMg ₂ (PO ₄ ) ₂ (UO ₂ ) ₂ P ₂ O ₇ , Ba ₂ Mg(PO ₄ ) ₂ (UO ₂ ) ₂ P ₂ O ₇ , Ba2UO2(VO4)2, or γ-Ba2UO2(PO4)2:Eu ³⁺ . [0044] The phosphors of the present disclosure may be characterized as uranium-doped or U-doped because the U ⁶⁺ ions are part of the emitting species. The term ‘U-doped’ typically indicates that a relatively small number of uranium atoms is substituted in the host lattice. In many compounds the uranium is present in the host lattice as the uranyl ion (UO2) ²⁺ . Because the uranyl ion is characterized by linear O-U-O bonding, there is typically an upper limit to the substitution that can be achieved, on the order of a few mole percent with respect to the site on which it is substituted. When substituting for a M ²⁺ ion there are size constraints between the M ²⁺ and the (UO2) ²⁺ center that may create host lattice strain and/or compensating defects in the host lattice. As a result, concentration quenching of the U ⁶⁺ emission usually occurs before full substitution is achieved. In contrast, the phosphors of the present disclosure contain the UO ₂ species as part of the host lattice and comprise uranyl ions at a concentration as high as about 40 mole% relative to the total number of moles of M ²⁺ cations present. [0045] The phosphors of the present disclosure may be produced by firing a mixture of precursors under an oxidizing atmosphere. Non-limiting examples of suitable precursors include the appropriate metal oxides, hydroxides, alkoxides, carbonates, nitrates, aluminates, silicates, citrates, oxalates, carboxylates, tartarates, stearates, nitrites, peroxides, phosphates, pyrophosphates and combinations thereof. Suitable materials for use as precursors include, but are not limited to, BaCO3, BaHPO4, Ba3(PO4)2, Ba2P2O7, Ba2Zn(PO4)2, BaZnP2O7, Ba(OH)2, Ba(C2O4), Ba(C2H3O2)2, Ba3(C6H5O7)2, Ba(NO3)2, CaCO3, Eu2O3, Mg(C2O4), Mg(C2H3O2)2, Mg(C6H6O7), MgCO3, MgO, Mg(OH)2, Mg3(PO4)2, Mg2P2O7, Mg2Ba(PO4)2, MgHPO4, Mg(NO3)2, NH4MgPO4, (NH4)2HPO4, NH ₄ VO ₃ , SrCO ₃ , Zn(C ₂ O ₄ ), Zn(C ₂ H ₃ O ₂ ) ₂ , Zn ₃ (C ₆ H ₅ O ₇ ) ₂ , ZnCO ₃ , ZnO, Zn(OH) ₂ , Zn3(PO4)2, Zn2P2O7, Zn2Ba(PO4)2, ZnHPO4, Zn(NO3)2, NH4ZnPO4, UO2, UO2(NO3)2, (UO ₂ ) ₂ P ₂ O ₇ , (UO ₂ ) ₃ (PO ₄ ) ₂ , NH ₄ (UO ₂ )PO ₄ , UO ₂ CO ₃ , UO ₂ (C ₂ H ₃ O ₂ ) ₂ , UO ₂ (C ₂ O ₄ ), H(UO2)PO4, UO2(OH)2, and ZnUO2(C2H3O2)4, and various hydrates. For example, the exemplary phosphor BaMgUO ₂ (PO ₄ ) ₂ may be produced by mixing the appropriate amounts of BaCO3, MgO, and UO2 with the appropriate amount of (NH4)2HPO4 and then firing the mixture under an air atmosphere. In another example, the exemplary gamma barium uranyl phosphate or gamma barium uranyl orthophosphate (γ-Ba2UO2(PO4)2) may be produced by mixing stochiometric amounts of BaHPO ₄ and UO ₂ with an excess of (NH ₄ ) ₂ HPO ₄ (DAP) and then firing the mixture under an air atmosphere. The precursors may be in solid form or in solution. Non-limiting examples of solvents include water, ethanol, acetone, and isopropanol, and suitability depends chiefly on solubility of the precursors in the solvent. After firing, the phosphor may be milled to break up any agglomerates that may have formed during the firing procedure. [0046] The mixture of starting materials for producing the phosphor may also include one or more low melting temperature flux materials, such as boric acid, borate compounds such as lithium tetraborate, alkali phosphates, and combinations thereof. Non- limiting examples include (NH4)2HPO4 (DAP). Li3PO4, Na3PO4, NaBO3-H2O, Li2B4O7, K ₄ P ₂ O ₇ , Na ₄ P ₂ O ₇ , H ₃ BO ₃ , and B ₂ O _3. The flux may lower the firing temperature and/or firing time for the phosphor. If a flux is used, it may be desirable to wash the final phosphor product with a suitable solvent to remove any residual soluble impurities that may have originated from the flux. [0047] The firing of the samples is generally done in air, but since the uranium is in its highest oxidation state (U ⁶⁺ ) it can also be fired in O2 or other wet or dry oxidizing atmospheres, including at oxygen partial pressures above one atmosphere, at a temperature between about 900°C and about 1300°C, particularly between about 1000°C and about 1200°C, for a time sufficient to convert the mixture to the phosphor. The firing time required may range from about one to twenty hours, depending on the amount of the mixture being fired, the extent of contact between the solid and the gas of the atmosphere, and the degree of mixing while the mixture is fired or heated. The mixture may rapidly be brought to and held at the final temperature, or the mixture may be heated to the final temperature at a lower rate such as from about 2°C/minute to about 200°C/minute. [0048] The phosphor compositions according to the present disclosure may include, in addition to the green-emitting phosphor, a red emitting phosphor of formula I: AxMFy:Mn ⁴⁺ (I), wherein A is Li, Na, K, Rb, Cs, or a combination thereof; M is Si, Ge, Sn, Ti, Zr, Al, Ga, In, Sc, Hf, Y, La, Nb, Ta, Bi, Gd, or a combination thereof; x is an absolute value of a charge of the MFy ion; and y is 5, 6 or 7. In one embodiment, the red emitting phosphor for formula I is A ₂ (MF ₆ ):Mn ⁴⁺ , where A is Li, Na, K, Rb, Cs, or a combination thereof; and M is Si, Ge, Sn, Ti, Zr, Al, Ga, In, Sc, Hf, Y, La, Nb, Ta, Bi, Gd, or a combination thereof. In particular, the red emitting phosphor may be K ₂ SiF ₆ :Mn ⁴⁺ . The red emitting phosphor of formula is radiationally and/or optically coupled to the LED light source. The phosphors of formula I are described in US 7,497,973, and US 8,906,724, and related patents assigned to the General Electric Company. Examples of the red emitting phosphors of formula I include, K ₂ (TiF ₆ ):Mn ⁴⁺ , K ₂ (SnF ₆ ):Mn ⁴⁺ , Cs2(TiF6):Mn ⁴⁺ , Rb2(TiF6):Mn ⁴⁺ , Cs2(SiF6):Mn ⁴⁺ , Rb2(SiF6):Mn ⁴⁺ , Na2(SiF6):Mn ⁴⁺ , Na ₂ (TiF ₆ ):Mn ⁴⁺ , Na ₂ (ZrF ₆ ):Mn ⁴⁺ , K ₃ (ZrF ₇ ):Mn ⁴⁺ , K ₃ (BiF ₇ ):Mn ⁴⁺ , K ₃ (YF ₇ ):Mn ⁴⁺ , K ₃ (LaF ₇ ):Mn ⁴⁺ , K ₃ (GdF ₇ ):Mn ⁴⁺ , K ₃ (NbF ₇ ):Mn ⁴⁺ or K ₃ (TaF ₇ ):Mn ⁴⁺ . In certain embodiments, the phosphor of formula I is K2SiF6:Mn ⁴⁺ . [0049] In addition to the green-emitting phosphor and, optionally, the red- emitting Mn ⁴⁺ doped phosphor of formula I, a phosphor composition according to the present disclosure may include one or more other luminescent materials. Additional luminescent materials such as blue, yellow, red, orange, or other color phosphors may be used in the phosphor composition to customize the white color of the resulting light and produce specific spectral power distributions.

Radiationally coupled or optically coupled means that radiation from the LED light source 12 is able to excite the phosphor composition 14, and the phosphor composition 14 is able to emit light in response to the excitation by the radiation. The phosphor composition 14 may be disposed on a part or portion of the LED light source 12 or located remotely at a distance from the LED light source 12. [0055] The general discussion of the example LED light source discussed herein is directed toward an inorganic LED based light source. However, as used herein, the term is meant to encompass all LED light sources such as semiconductor laser diodes (LD), organic light emitting diodes (OLED) or a hybrid of LED and LD. In addition, the LED light source may be a miniLED or microLED, which may be used in self-emissive displays. Further, it should be understood that the LED light source may be replaced, supplemented or augmented by another radiation source unless otherwise noted and that any reference to semiconductor, semiconductor LED, or LED chip is merely representative of any appropriate radiation source, including, but not limited to, LDs and OLEDs. In some embodiments, the phosphor composition 14 further includes a red emitting phosphor of formula I, particularly K ₂ SiF ₆ :Mn ⁴⁺ . [0056] The phosphor composition 14 may be present in any form such as powder, glass, or composite e.g., phosphor-polymer composite or phosphor-glass composite. Further, the phosphor composition 14 may be used as a layer, sheet, strip, dispersed particulates, or a combination thereof. In some embodiments, the phosphor composition 14 includes the green-emitting phosphor in glass form. In some of these embodiments, the device 10 may include the phosphor composition 14 in form of a phosphor wheel (not shown). The phosphor wheel may include the green-emitting phosphor embedded in a glass. A phosphor wheel and related devices are described in WO 2017/196779. [0057] FIG. 2 illustrates a lighting apparatus or lamp 20, in accordance with some embodiments. The lighting apparatus 20 includes an LED chip 22, and leads 24 electrically attached to the LED chip 22. The leads 24 may comprise thin wires supported by a thicker lead frame(s) 26 or the leads 24 may comprise self-supported electrodes and the lead frame may be omitted. The leads 24 provide current to LED chip 22 and thus cause it to emit radiation. [0058] A layer 30 of a phosphor composition including the green-emitting phosphor is disposed on a surface of the LED chip 22. The phosphor layer 30 may be disposed by any appropriate method, for example, using a slurry prepared by mixing silicone and the phosphor composition. In one such method, a silicone slurry in which the phosphor composition particles are randomly suspended is placed around the LED chip 22. This method is merely exemplary of possible positions of the phosphor layer 30 and LED chip 22. The phosphor layer 30 may be coated over or directly on the light emitting surface of the LED chip 22 by coating and drying the slurry over the LED chip 22. The light emitted by the LED chip 22 mixes with the light emitted by the phosphor composition to produce desired emission. [0059] With continued reference to FIG. 2, the LED chip 22 may be encapsulated within an envelope 28. The envelope 28 may be formed of, for example glass or plastic. The LED chip 22 may be enclosed by an encapsulant material 32. The encapsulant material 32 may be a low temperature glass, or a polymer or resin known in the art, for example, an epoxy, silicone, epoxy-silicone, acrylate or a combination thereof. In an alternative embodiment, the lighting apparatus 20 may only include the encapsulant material 32 without the envelope 28. Both the envelope 28 and the encapsulant material 32 should be transparent to allow light to be transmitted through those elements. [0060] In some embodiments as illustrated in FIG. 3, a phosphor composition 33 green-emitting phosphor is interspersed within the encapsulant material 32, instead of being formed directly on the LED chip 22, as shown in FIG. 2. The phosphor composition 33 may be interspersed within a portion of the encapsulant material 32 or throughout the entire volume of the encapsulant material 32. Blue light emitted by the LED chip 22 mixes with the light emitted by phosphor composition 33, and the mixed light transmits out from the lighting apparatus 20. [0061] In yet another embodiment, a layer 34 of the phosphor composition including the green-emitting phosphor, is coated onto a surface of the envelope 28, instead of being formed over the LED chip 22, as illustrated in FIG. 4. As shown, the phosphor layer 34 is coated on an inside surface 29 of the envelope 28, although the phosphor layer 34 may be coated on an outside surface of the envelope 28, if desired. The phosphor layer 34 may be coated on the entire surface of the envelope 28 or only a top portion of the inside surface 29 of the envelope 28. The UV/blue light emitted by the LED chip 22 mixes with the light emitted by the phosphor layer 34, and the mixed light transmits out. Of course, the phosphor composition may be located in any two or all three locations (as shown in FIGs. 2-4) or in any other suitable location, such as separately from the envelope 28 or integrated into the LED chip 22. [0062] In any of the above structures, the lighting apparatus 20 (FIGS. 2- 4) may also include a plurality of scattering particles (not shown), which are embedded in the encapsulant material 32. The scattering particles may comprise, for example, alumina, silica, zirconia, or titania. The scattering particles effectively scatter the directional light emitted from the LED chip 22, preferably with a negligible amount of absorption. [0063] Some embodiments include a surface mounted device (SMD) type light emitting diode 50, e.g. as illustrated in FIG. 5, for backlight applications. This SMD is a “side-emitting type” and has a light-emitting window 52 on a protruding portion of a light guiding member 54. An SMD package may comprise an LED chip as defined above, and a phosphor composition including the green-emitting phosphor as described herein. [0064] Devices of the present disclosure include lighting and display apparatuses for general illumination and display applications. Examples of display apparatuses include liquid crystal display (LCD) backlight units, televisions, computer monitors, laptops, mobile phones, smartphone, tablet computers and other handheld devices. Where the display is a backlight unit, the green-emitting phosphor may be incorporated in a sheet or strip that is radiationally coupled and/or optically coupled to the LED light source, as described in US Patent Application Publication No. 2017/0254943. Examples of other devices include chromatic lamps, plasma screens, xenon excitation lamps, UV excitation marking systems, automotive headlamps, home and theatre projectors, laser pumped devices, and point sensors. [0065] By use of the phosphor compositions described herein, devices can be provided producing white light for display applications, for example, LCD backlight units, having high color gamut and high luminosity. Alternately, devices can be provided producing white light for general illumination having high luminosity and high CRI values for a wide range of color temperatures of interest (2500 K to 10000 K). The list of these applications is meant to be merely exemplary and not exhaustive. [0066] Although specific features of various embodiments of the disclosure may be shown in some drawings and not in others, this is for convenience only. In accordance with the principles of the disclosure, any feature of a drawing may be referenced and/or claimed in combination with any feature of any other drawing.

Example 17: Gamut coverage of phosphor blends [0088] Blend simulations using (u,v) or (x,y) color space were calculated using the spectra of a 450 nm blue LED and PFS (K ₂ SiF ₆ :Mn ⁴⁺ ) passing through standard LCD color filters. The color filter (CF) set and optical density of the CF set were kept constant, so that the results of the modeling only showed the effect of changing the green phosphor. The blend ratios of the LED and green and red phosphors were varied so that the output of the emission after going through the optical stack and color filter set were at the same D65 color point and then gamut area coverages were calculated. Results are shown in Table 2.
