Rb+ cations enable the change of luminescence properties in perovskite (RbxCs1-xPbBr3) quantum dots.

Abstract

All-inorganic metal halide perovskites of the formulation ABX3 (where A is Cs+, B is commonly Pb2+, and X is a halide, X = Cl, Br, I) have been studied intensively for their unique properties. Most of the current studies focus on halogen exchange to modify the luminescence band gap. Herein we demonstrate a new avenue for changing the band gap of halide… (More)
