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

Fig. 1

Single crystal X-ray structures: octahedral arrangements in (a) Cs2AgIn0.5Bi0.5Cl6, (b) Cs2AgIn0.5Sb0.5Cl6, and(c) Cs2AgSb0.5Bi0.5Cl6 halide double perovskites compounds. (d) Calculated lattice parameters for Cs2AgInxBi1−xCl6, Cs2AgInxSb1−xCl6, and Cs2AgSbxBi1−xCl6 for various x values. (e) Raman spectra of Cs2AgInxBi1−xCl6 powders for selected x values (0, 0.6, 0.8, and 1).
