A Robust Zero-Dimensional Hybrid Bismuth Chloride with Highly Efficient White Light Emission
Source abstract
Abstract
Although organic–inorganic hybrid metal halides have made great progress in the field of luminescence, the quest for corresponding white-light-emitting solids with high photoluminescence quantum yield (PLQY) and an excellent color rendering index (CRI) is still ambitious. Bismuth is a reliable and promising alternative to lead halides, but undoped bismuth halides with efficient white light are especially rare. Herein, we report a zero-dimensional (0D) metal halide, namely, [H 2 DPA]BiCl 5 (DPA = di(2-picolyl)amine) featuring white-light emission with a high PLQY of 26.93% and a CRI of 88, which could be attributed to the synergistic interaction of inorganic and organic units. Remarkably, the compound exhibits considerable structural and spectral stability, showing potential application in white-light-emitting devices.
