Lead-free hybrid indium perovskites with near-unity PLQY and white light emission using an Sb3+ doping strategy

A series of new Sb 3+ doped-(DETA)InCl 6 organic–inorganic hybrid metal halide single crystals were synthesized. The PLQY of single crystals doped with 10% Sb was up to 100%, and white light emission was achieved when the Sb doping amount was 0.005%.
