Inorganic halide perovskite CsPbX3(X=Cl,Br,I) nanocrystals(NCs) have been received much concern because it owns many excellent optical properties, such as high quantum yield(~90%), the emission wavelength covering the entire visible light region(400~700 nm), and the narrow full width at half maximum(12~42 nm). These advantages make it becomes one of the luminescence materials which have the most potential applications. Therefore, in recent years, reports involving inorganic halide perovskite materials become more and more. In this review, the development history, the synthetic routes, structures, growth mechanisms, and applications of inorganic halide perovskite NCs that make them excellent optoelectronic materials for various strategies are mainly discussed and highlighted. The existing problems of inorganic halide perovskite luminescence materials under the current research backgrounds are summarized. Finally, perspectives on future exploration of inorganic halide perovskite NCs for photoelectric devices are also given.
