  Manipulation of parity and polarization through structural distortion in light-emitting halide double perovskites

  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.
