Although silver surface provides very intense signal of surface-enhanced Raman scattering, the surface is not unstable in acid such as hydrochloride, limiting the ambient for SERS. Graphene is chemically stable and prohibits penetrations of small molecules like H₂ and water. We demonstrated that a graphene-coated silver thin film on silicon dioxide has stable SERS in hydrochloride solution.
