Abstract

Surface-enhanced Raman scattering (SERS) has been detected for pyridine adsorbed onto the surface of thin (average thickness = 2.0 to 8.8 nm), continuous layers of stainless steel that were laser ablated onto roughened electrodes of silver. The experiments were performed on samples immersed in 0.1M KCl + 0.05M pyridine. The SER spectra changed with applied potential, and the intensities of the spectra decreased with increasing thickness of stainless steel. This procedure opens up SERS to the study of electrochemical phenomena at interfaces between alloys and a wide range of aqueous/gaseous environments
