In this study, a hybrid nanostructure of AgNPs@G was designed considering taking advantage of both the electromagnetic enhancement mechanism (EM) and chemical enhancement mechanism (CM) thanks to AgNPs and CVD growth graphene via a single-step fabrication. The size distribution of AgNPs with a perfect single crystalline structure obtained as 2-10 nm and uniformly decorated on CVD graphene surface. The excellent integration of AgNPs and graphene has been confirmed by TEM and XPS studies. The SERS activity of the fabricated AgNPs@G nanocomposite has been examined using Rhodamine 6G (R6G) as a probe molecule with different concentrations. The value of enhancement factor (EF) calculated as 7.2 x 10(4) suggests that the AgNPs@G nanostructure substrates have perfect SERS properties. The results in this paper demonstrate that the fabricated hybrid nanostructure AgNPs@G can be promising SERS substrate in many practical applications.eninfo:eu-repo/semantics/closedAccessAg NanoparticlesChemical Vapor DepositionGrapheneSersA single-step fabrication of Ag nanoparticles and CVD graphene hybrid nanostructure as SERS substrateArticle2332-s2.0-85090745243Q2WOS:000577077900003Q210.1016/j.mee.2020.111421
