Abstract

A study of the effects of laser wavelength and power density during controlled-rate illuminated oxidation-reduction cycles (ORCs) of Ag electrodes on the surface-enhanced Raman scattering (SERS) intensity of the v(Ag-Cl) band is reported. SERS spectra were acquired with a constant excitation wavelength after illuminated ORCs to deconvolute the SERS excitation behavior from the ORC illumination effects. Enhancement of SERS intensities is greater for illumination in the blue and green wavelength regions than for illumination in the red wavelength region. This enhancement is selective for the illumination position on the Ag electrode during the ORC. These results suggest the enhancement results from a photoeffect analogous to latent image formation in silver halide photography.
