Enhancing broadband blue luminescence efficiency and stability in Bi3+-doped Cs2ZnCl4 nanocrystals from STEs and advancing energy applications

Lead-halide perovskites exhibit excellent photovoltaic properties. However, lead's toxicity and limited stability under ambient conditions limit its further commercialization. This paper reports a Bi3+-doped lead-free metal halide, Cs2ZnCl4:Bi3+ nanocrystals (NCs). After doping with Bi3+, the p...
