Electrochemical synthesis of luminescent MoS2 quantum dots

Author affiliations

Abstract

Size-controlled synthesis of luminescent quantum dots of MoS2 (≤2 layers) with narrow size distribution, ranging from 2.5 to 6 nm, from their bulk material using a unique electrochemical etching of bulk MoS2 is demonstrated. Excitation-dependent photoluminescence emission is observed in the MoS2 QDs. “As-synthesized” MoS2 QDs also exhibit excellent electrocatalytic activity towards hydrogen evolution reactions.
