摘要：
Graphene nanosheets have been widely used to study the surface-enhanced Raman scattering (SERS) enhancement mechanism. However, the effect of graphene on the field distribution in specific nanocomposite structures was unclear. Therefore, it is important to study the effect of reduced graphene oxide (rGO) in metal semiconductor core-shell structures based on SEAS. The enhancement factors (EF) was changed significantly in the presence and absence of the rGO substrate with the green and red laser excitations. Experimental and theoretical simulations results demonstrate that rGO platform plays an important role in enhancing SEAS activity of single Ag@Cu2O core-shell particles. This research with respect to rGO-based SEAS substrates will expand the basic theoretical research of nanomaterials and provide a theoretical basis for optoelectronic research.
