摘　　要：In recent two years,organometal halide perovskites quantum dots are emerging as a new member of the nanocrystals family.From the chemical point of view,these perovskites quantum dots can be synthesized either by classical hot-injection technique for inorganic semiconductor quantum dots or the reprecipitation synthesis at room temperature for organic nanocrystals.From a physical point of view,the observed large exciton binding energy,well self-passivated surface,as well as the enhanced nonlinear properties have been of great interest for fundamental study.From the application point of view,these perovskites quantum dots exhibit high photoluminescence quantum yields,wide wavelength tunability and ultra-narrow band emissions,the combination of these superior optical properties and low cost fabrication makes them to be suitable candidates for display technology.In this short review,we introduce the synthesis,optical properties,the prototype light-emitting devices,and the current important research tasks of halide perovsktie quantum dots,with an emphasis on CH_3NH_3PbX_3（X= CI,Br,I） quantum dots that developed in our group.In recent two years,organometal halide perovskites quantum dots are emerging as a new member of the nanocrystals family.From the chemical point of view,these perovskites quantum dots can be synthesized either by classical hot-injection technique for inorganic semiconductor quantum dots or the reprecipitation synthesis at room temperature for organic nanocrystals.From a physical point of view,the observed large exciton binding energy,well self-passivated surface,as well as the enhanced nonlinear properties have been of great interest for fundamental study.From the application point of view,these perovskites quantum dots exhibit high photoluminescence quantum yields,wide wavelength tunability and ultra-narrow band emissions,the combination of these superior optical properties and low cost fabrication makes them to be suitable candidates for display technology.In this short review,we introduce the synthesis,optical properties,the prototype light-emitting devices,and the current important research tasks of halide perovsktie quantum dots,with an emphasis on CH_3NH_3PbX_3（X= CI,Br,I） quantum dots that developed in our group.
