[en] In the past five years, all-inorganic metal halide perovskite (CsPbX₃, X = Cl, Br, I) nanocrystals have been intensely studied due to their outstanding optical properties and facile synthesis, which endow them with potential optoelectronic applications. In order to optimize their physical and chemical properties, different strategies have been developed to realize the controllable synthesis of CsPbX₃ nanocrystals. In this short review, we firstly present a comprehensive and detailed summary of existed synthesis strategies of CsPbX₃ nanocrystals and their analogues. Then, we introduce the regulations of several reaction parameters and their effects on the morphologies of CsPbX₃ nanocrystals. At the same time, we provide stability improvement methods and representative applications. Finally, we propose the current challenges and future perspectives of the promising materials. (paper)
