Abstract

Read online

Halide perovskites recently attracted wide attention for light emitting applications. Here, octahedral distortion in halide double perovskites Cs2AgMCl6, induced by the mixture of trivalent M-cations Bi3+, In3+, and Sb3+, gives rise to enhanced white light emissivity and longer photoluminescence lifetimes.
