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.
