摘　　要：CsPbX_(3)(X=Cl,Br,I)量子点微晶玻璃集CsPbX_(3)量子点出众的光学性能和玻璃良好的物化性能于一体,在光学数据存储、随机激光、X射线成像、照明显示、太阳能电池、光催化等领域有重要应用价值。本文概述了其制备加工以及相对应的性能应用的最新进展,如利用飞秒激光加工在玻璃中指定区域析出CsPbX_(3)用作光学数据存储,以此刻画其组成-结构-性能之间关系与变化规律。不过,其在未来的研究中仍面临诸多挑战,如CsPbX_(3)在玻璃基质中的原位生长机理并不完全清楚,对CsPbX_(3)前驱体在“玻璃微反应器”中的赋存状态、近邻结构和分布形态的研究将有助于进一步认识CsPbX_(3)在玻璃中的形成机理,为获得光学性能更好的CsPbX_(3)量子点微晶玻璃提供理论指导。CsPbX_(3)(X=Cl,Br,I)perovskite quantum dots embedded glass-ceramics(GCs)are a composite material with the steady physical and chemical properties of glass matrix phase and the superior optical performance of CsPbX_(3) quantum dot phase.These materials are used in optical data storage,random laser,X-ray image,lighting and display,solar cells,photocatalysis,etc..Recent advances on the preparation and the corresponding performance/application were introduced,i.e.,the use of fs laser to form CsPbX_(3)in selected zone to serve as optical data storage,thereby showing the regular pattern of these materials’composition-structureperformance relationship.Nevertheless,these are some challenges of investigating for these materials,i.e.,the in-situ formation of CsPbX_(3) in glass matrix is entirely unclear.And the studies on CsPbX_(3) precursors’occurrence state,neighbor structure and morphological distribution could further help to understand the formation mechanism of CsPbX_(3) in glass,providing a guide to obtain the better CsPbX_(3) perovskite quantum dots embedded GCs.
