Abstract

Though the SERS effect based on pristine MoS₂ is hardly observed, however, the plasma treated MoS₂ nanoflakes can be used as an ideal substrate for surface enhanced Raman scattering. It is proved that the structural disorder induced generation of local dipoles and adsorption of oxygen on the plasma treated MoS₂ nanosheets are the two basic and important driven forces for the enhancement of Raman signals of surface adsorbed R6G molecules.
