Abstract

We report the fabrication of large area SERS substrates based on anodic porous alumina template over which gold thin layer of 25 nm was deposited. A specific design of honey-comb structure with the pore size/cell thickness of 60/40 nm was attained by using the controlled electrolyte potential, time of etching and oxalic acid as an electrolytic solution. Cresyl violet and glycine molecules were deposited through chemisorption technique to verify the SERS substrate functionality. Numerical simulations in order to describe the realistic device were also carried out, finding consistency with the experimental results.
