摘要： Recent breakthroughs in hot carrier (HC) cooling dynamics within halide perovskite nanocrystals (NCs) have positioned them as promising candidates for next-generation optoelectronic applications. Therefore, it is of great importance to systematically summarize advances in understanding and controlling HC relaxation mechanisms. Here, we offer an overview of advances in the understanding of the HC cooling process in perovskite NCs, with a focus on influences of excitation energy, excitation intensity, composition, size, dimensionality, doping, and core-shell structure on the HC cooling times. Finally, we propose suggestions for future investigations into the HC cooling process in perovskite NCs.
