Title:
LIGHT EMITTING DIODE, METHOD FOR PREPARING SAME, AND LIGHT EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/211127
Kind Code:
A1
Abstract:
A light emitting diode, a method for preparing same, and a light emitting device. The light emitting diode comprises a cathode (107), an anode (101), and a functional layer located between the cathode (107) and the anode (101). The functional layer comprises at least one of a hole transport layer (103) and an electron transport layer (105), and a light emitting layer (104). At least one of the hole transport layer (103) and the electron transport layer (105) comprises a material of a perovskite structure. The general formula of the material of a perovskite structure is ABX3, wherein A is RNH3 or Cs; R is CnH2n+1, n≥1; X is at least one of Cl, Br, and I; B is at least one of plumbum (Pb), germanium (Ge), bismuth (Bi), stannum (Sn), cooper (Cu), manganese (Mn), and stibium (Sb). The light emitting diode is capable of reducing the driving voltage of a light emitting device, reducing power consumption of the light emitting device, and prolonging the service life of the device.
