Description
Summary:Recently, all-inorganic cesium lead halide (CsPbX 3 , X = Cl, Br, I) perovskite nanocrystals (NCs) have attracted much attention because of their excellent photophysical properties and promising applications in diverse fields. In this review article, the synthetic methods have been briefly summarized first, followed by the morphological control of CsPbX 3 NCs. To improve their photophysical properties as well as stability, surface passivation strategies, such as chemical treatment and encapsulation approaches, are used and have been summarized. Their representative applications in various fields, including light emitting diodes (LEDs), solar cells, photodetectors, lasers and photocatalysis, have been introduced. Finally, a brief outlook of this field has been proposed to point out some important challenges and possible solutions. The synthetic approaches, morphological control, passivation methods, applications and outlook of CsPbX 3 nanocrystals have been summarized in this article.
