Linking the pyramid distortion to luminescence in Sb-based metal halide by best fitted ideal polyhedron characterization†
Abstract
Sb-based metal halides have been a research focus because of their excellent optical properties. Pyramid-like [SbCl5] polyhedra are the most distinct crystallographic feature. We analyzed 56 luminescent Sb-based hybrids from a list of 120 Sb chlorides by finding the corresponding best fitted ideal polyhedron. The results show a significant correlation between the distortion and photoluminescent quantum yield.
