Abstract

Surface enhanced Raman spectroscopy (SERS) is a novel non-destructive, accurate and rapid detection technology. However, the traditional SERS substrate has the problems of high cost,low efficiency and non-reusability, which limits its practical application. In recent years, researchers are increasingly interested in combining semiconductor materials with noble metal materials. In this report, Au-decorated ZnO nanorods are fabricated on copper sheet (Au/ZNRs/Cu) as a self-cleaning SERS substrate. The ZnO nanorods are prepared by hydrothermal approach. Then the obtained nanostructure is decorated with Au NPs through sputtering. The prepared substrate can detect R6G with a detection limit of 10^-7M. After 30 min of UV irradiation, 85% of R6G molecules is removed.
