Lead halide perovskite nanocrystals have attracted attention as luminescent materials for next generation displays, however, their stability and blue emission efficiency remain challenging. In this study, CsPbBr3 quantum dots were synthesized at low temperature under liquid-nitrogen conditions, and blue emission around 456 nm with a high photoluminescence quantum yield was achieved through controlled crystal growth.
