Title:
RED PHOSPHOR POWDER AND PREPARATION METHOD AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/012393
Kind Code:
A1
Abstract:
The present invention relates to a red phosphor powder and a preparation method and application thereof, belonging to the technical field of phosphors used for light-emitting diodes (LEDs) in the field of lighting and display. The present invention uses a compound containing molybdenum ions as a matrix, doped with rare earth element europium ions, yttrium ions, and alkali metal ions to prepare a red phosphor, having the chemical formula MnY1-xEux(MoO4)2 (M is alkaline metal; n = 0.10–1.5; x = 0.1–0.5). The red phosphor prepared by the present invention can be simultaneously excited by ultraviolet light, blue light, and green light to effectively excite red light having a higher luminous intensity; the preparation process of the molybdate red phosphor provided by the invention is simple, and the process is easy to operate and suitable for use in industrial production.
