In article number 1901338, Bayrammurad Saparov and co‐workers introduce a family of nontoxic all‐inorganic halides Rb 2 CuX 3 (X = Br, Cl), prepared by using high temperature and solution techniques. The materials exhibit one‐dimensional crystal structures and show high photoluminescence quantum yield blue emission up to unity attributed to self‐trapped excitons. Single crystals of Rb 2 CuCl 3 have also been shown to demonstrate an up‐conversion photoluminescence, the first example of such behavior for a Pb‐free metal halide.
