Chelating-agent-assisted control of CsPbBr3 quantum well growth enables stable blue perovskite emitters

Metal halide perovskites have been studied as promising materials for blue light-emitting diodes (LEDs) but the stability is still a bottleneck. Here Wang et al. develop a chelating additive strategy to increase efficiency, operational stability and color stability of blue perovskite LEDs.
