Preparation of Ag nanosheet hierarchical clubbed micro/nanostructured arrays and their application based on the SERS effect

Ag nanosheet hierarchical clubbed micro/nanostructured arrays (HCMNs) were prepared through two-step electrodeposition method on an ITO conduction glass coated ZnO seed layer (ZSL), the clubbed arrays were formed by the Ag nanosheets electrodeposited on the ZnO nanorods . Such arrays exhibit excellent surface-enhanced Raman scattering (SERS) performance including high activity and sensitivity, biological solubility and stability, and can be used as SERS substrate for trace analysis and detection of some chemicals. It was proved that their SERS detecting limit of R6G solution can be to10 −12  M, indicating the practical applications based on the SERS effect of noble-metal/semiconduct composite micro/nanostructured arrays.
