Tóm tắt

Iodide-bromide mixed perovskites have attracted significant attention for achieving pure-red emission. However, halide migration hinders the development of efficient and stable devices. We introduce an in situ crystallization regulation strategy using post-annealing to optimize pure-red CsPb(Br/I)
