摘　　要：有机-无机金属卤化物作为一种新兴的发光材料,由于其高的发光效率以及宽的发射光谱等优点受到广泛关注。本文以有机-无机金属卤化物高效荧光材料为对象,根据金属阳离子种类对材料进行归类,探讨其高效发光机理,并提出改善该类材料发光效率的方法。总体而言,对于此类荧光材料的研究还处于起步阶段,其发光机理仍然存在争议,本文对当前主流发光机理进行了总结。最后,对于有机-无机金属卤化物荧光材料的发展前景进行了展望,旨在进一步推动该类材料在荧光转换发光二极管等领域的应用。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 lightemitting diodes.
