Abstract:
Phase-pure all-inorganic zero-dimensional (0D) tin halide Cs4SnX6 (X = Br, I) nanocrystals (NCs) are successfully prepared for the first time. The as-prepared Cs4SnBr6 NCs exhibit a strongly Stokes-shifted broadband emission with a high photoluminescence quantum yield (PLQY) of 21% at room temperature.
