A facile, environmentally friendly synthesis of strong photo-emissive methylammonium lead bromide perovskite nanocrystals enabled by ionic liquids

Abstract

Herein we demonstrate a new method for the synthesis of methylammonium lead bromide perovskite nanocrystals (MAPbBr₃) by using environmentally friendly ionic liquids. The effects of different carboxylate anions in ionic liquids on crystal growth and the properties of MAPbBr₃ were investigated. This work paves a new avenue for the sustainable synthesis of perovskite materials by using ionic liquid based green solvents.
