Dependence of the Efficiency of Enhanced Raman Scattering on the Period of the Electrochemical Deposition of Nanowires in Pores of Track-Etched Membranes

Abstract Results are presented from studying the optical characteristics of nanostructured surfaces obtained via electrochemical deposition in pores of track-etched membranes. Such structures display a pronounced effect of enhancing Raman scattering from the molecules adsorbed on their surface. Rhodamine 6G and Malachite Green dyes are used as model compounds to estimate the efficiency of enhancement. The dependence between the parameters of synthesis of nanowires and the degree of signal enhancement is established experimentally, allowing the optimum conditions for obtaining SERS-active substrates to be determined.
