Abstract

The fabrication of a three-dimensional (3D) ordered array of metal and/or metal oxide nanoparticles in an anodic porous alumina matrix and the application of a 3D array of Au nanoparticles as a substrate for the measurement of surfaceenhanced Raman scattering (SERS) are discussed. The 3D structure is prepared by a repeated process composed of the formation of nanoholes by the anodization of Al and the subsequent electrochemical deposition of a metal into the holes. The dependence of the SERS intensity on the number of layers of the Au nanoparticle array was examined. In addition, the effect of the gap size between Au nanoparticles was also investigated. The present process allows the fabrication of 3D functional optical devices based on the enhancement of the electric field of incident light.
