Subject of study. Lead-free perovskite nanocrystals (LFPNCs), their main characteristics, synthesis methods, and optical properties are examined. Aim The aim is to analyze the state-of-the-art research data on methods LFPNCs. In addition, formation processes LFPNCs, dependence nanocrystal size photoluminescence quantum yield (PLQY) parameters (such as method, temperature, ligand type) determined. Main results. LFPNCs analyzed based LaMer cluster growth models. According data, primary for preparing these (NCs) hot-injection ligand-assisted reprecipitation (LARP). Evidently, average increases with increasing reaction temperature. For NCs synthesized by LARP, temperature 100°C leads a slight decrease in yield. However, prepared hot-injection, PLQY remains independent Additionally, using oleic acid results narrow distribution NCs, whereas mixture ligands exhibiting highest PLQY. Practical significance. literature analysis show that LARP method most promising synthesizing owing its ease implementation, energy efficiency, scalability. produced this can be applied active materials sensor technologies, photovoltaics, optoelectronic devices.
