Cesium lead halide (CsPbX₃) perovskite nanocrystals (NCs) are of great interest for next‐generation optoelectronics because of its excellent optical properties and exceptional colour tunability. Nevertheless, these materials suffer degradation which has become a major challenge for their use in practical applications. Researchers mainly focused on developing various approaches to improve the photoluminescence properties and stability of CsPbX₃ perovskite NCs. Among these, herein, we review some of the promising approaches to address the challenges like post‐synthetic modification, ligand exchange, and in situ addition.
