Abstract: A simple chemical method for preparing SERS active surfaces was developed by etching silver foils in concentrated HNO_3 solutions. The enhancement factors were calculated to be 10~6 as compared with solution spectra. The technique was applied to investigate the self-assembly of benzyl disulfide and adsorption orientation of thiophenol on silver surfaces. The results show that the HNO_3 roughened silver foil seems to be a more routinely preparable substrate system for SERS study.
