In the past few years, metal halide perovskite quantum dots and nanocrystals have been extensively explored due to their unique optoelectronic properties and extensive application prospects. In this review article, we provide an overview of the synthesis, microstructure variation, luminescence properties and potential applications of hybrid organic–inorganic perovskites and all-inorganic perovskites. Firstly, several widely used wet chemical methods for synthesizing perovskite quantum dots are summarized, and then the related structures and morphologies of different perovskites as well as the relationship between the microstructure and optical properties are given. Additionally, correlative metal halides with B-site ion replacement or doping and some strategies to improve the stability of perovskite materials are highlighted. Subsequently, a brief introduction about their potential applications in light-emitting diodes, photodetectors and lasing is presented. Finally, some conclusions and outlooks will be introduced. It is expected that this review article will provide valuable insights into the current status of perovskite luminescent materials and stimulate new ideas and further research on their practical applications.
