Highly efficient luminescence and color-tunable white emission from 0D Cs2InCl5·H2O perovskites via Al3+ and Sb3+ codoping

The Al 3+ –Sb 3+ co-doped Cs 2 InCl 5 ·H 2 O exhibits bright broadband emission (PLQY~80%) with luminescence color closes to standard white light. Further, by changing the concentration of Al 3+ , precise control of the luminescence color is achieved.
