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.
