Abstract

Surface enhanced fluorescence and surface enhanced resonance Raman scattering (SERRS) of the dye basic fuchsin are observed on Ag electrode surfaces which have been electrochemically roughened with an oxidation-reduction cycle (ORC) in the presence of basic fuchsin and 0.1 M KC1. The fluorescence of the dye on the Ag surface is red shifted by ca. 26 nm relative to solution fluorescence, and as time passes, the fluorescence broadens into the blue region of the spectrum. The enhancement factor is ca. 26 ± 10 for a vertically oriented monolayer of the dye on the roughened Ag electrode. Scanning electron microscopy (SEM) indicates that unique roughness features are formed during the ORC in the presence of the dye. These features appear to be necessary for surface enhanced fluorescence.
