Aggregation-induced emission properties of hydrothermally synthesized Cu–In–S quantum dots

Abstract

Novel Cu–In–S quantum dots (CIS QDs), which exhibit interesting aggregation-induced emission (AIE) properties, were successfully prepared via a hydrothermal method. When the solvent was changed from water to 90 vol% DMSO, the photoluminescence intensity of the as-prepared CIS QDs was enhanced about 126-fold.
