In recent years, metal halide perovskites have emerged as one of the most promising light-emitting materials owing to their high color purity and tunability. In addition, their favorable optoelectrical properties have enabled their use in a wide variety of applications, such as photovoltaics and light-emitting diodes (LEDs). In particular, bright luminescent colloidal nanocrystals (NCs) show considerable potential for LEDs applications. However, the low stability and durability of perovskite NCs hamper their commercialization. Therefore, post-synthetic surface modification of perovskite NCs has become an important strategy for achieving not only excellent optical properties but also high-efficiency LEDs. Techniques such as ligand exchange, anion exchange, metal doping, and novel purification processes have been demonstrated to passivate surface defects and remove impurities from the NCs. In this review, we summarize our recent work on post-synthetic surface modification treatments of perovskite NCs toward achieving highly efficient LEDs.
