Tuning photoluminescence of single-layer MoS2 using H2O2

Author affiliations

Abstract

Enhancing photoluminescence (PL) of single-layer (1L) MoS2 is critical to its application as the thinnest light-emitting material. In this report, we show that the PL intensity of 1L-MoS2 can be enhanced by 8 times using physisorption of H2O2 molecules as p-type dopants. By using toluene to form the sandwiched structure of H2O2/1L-MoS2/toluene, the PL intensity of 1L-MoS2 can be enhanced up to 27.4 times. Our research proposes a simple but effective method to enhance the light emitting properties of 1L-MoS2.
