An effective approach is proposed for fabrication of ZnO/Ag nanocomposite for surface
enhanced Raman scattering application by combining hydrothermal assisted with galvanic
effect and sputtering process. The sputtering process is applied to distribute Ag on the
surface of ZnO nanostructures. The morphology, structure, elemental composition and
optical properties of the samples were studied. The most suitable sputtering condition was
identified to achieve the highest Raman enhancement. The optimum sputtering time of 70 s …
