Ag-Cu Nanoparticles Encaptured by Graphene with Magnetron Sputtering and CVD for Surface-Enhanced Raman Scattering
Source abstract
Abstract
An efficient surface-enhanced Raman scattering (SERS) substrate has been developed based on Ag-Cu nanoparticle-decorated graphene. The Ag-Cu-graphene (Ag-Cu@G) hybrid structure was prepared by magnetron sputtering for Ag and Cu film and chemical vapor deposition (CVD) for graphene, which avoided defects produced by graphene transferring process. The hybrid materials were confirmed by scanning electron microscopy (SEM), atomic force microscopy (AFM), energy dispersive spectroscopy (EDS), and Raman spectroscopy. With R6G as analyst molecule, the enhancement factor (EF) of the order of 106 for Ag-Cu@G sample was obtained. Meanwhile, the substrates had stable enhanced SERS signals after 78-day exposure in air, which could be explained by the fact that the graphene is efficient at maintaining chemical and optical stability. The formation of graphene can contribute a stabilization and fluorescence quenching effect. Moreover, the electromagnetic distribution based on AFM images was simulated by finite difference time domain (FDTD) method.
