This work aims to study the possibility of using SiO2/n-Si porous template to the formation of copper nanostructures with different morphology for the surface-enhanced Raman spectroscopy (SERS) applications. Porous SiO2/n-Si templates were obtained using swift heavy ion-track technology including irradiation and chemical etching. The influence of the ion energy on the process of latent track formation was discussed. The dependences of pores template parameters on the irradiation fluence and etching time were investigated. In the pores of the SiO2/n-Si template by the electrodeposition method, spatially separated copper nanostructures with different morphology (compact deposit and dendrites) have been formed. Morphological and structural characteristics of SiO2(Cu)/n-Si nanostructures were studied. The possibility of tailoring of copper nanostructures shape by variation of deposition potential was shown. An analysis of the efficiency of the SERS using the water solution of the model analyte Rhodamine 6G was made. The potential of using copper dendrites for the SERS was discussed.
