High-Efficiency and Broad-Spectrum Emitting Organic-Inorganic Metal Halide Photoluminescent Materials

Organic. inorganic metal halides, as an emerging photoluminescent material, have received extensive attention due to their high photoluminescence quantum yield and broad. spectrum emission. This paper focuses on organic. inorganic metal halide high-efficiency photoluminescent materials, classifies the materials according to the types of metal cations, discusses their high-efficiency luminescent mechanism, and proposes methods to improve the luminous efficiency of such materials. In general, the research on such photoluminescent materials is still in its infancy, its light. emitting mechanism is still controversial, and current mainstream light. emitting mechanisms are summarized. Finally, the development prospects of organic. inorganic metal halide photoluminescent materials are prospected, aiming to further promote the application of this type of material in the field of phosphor-converted light. emitting diodes.
