Abstract

A study has been performed in which the SERS intensity of the pyridine ring breathing vibration at 1008 cm^-1 at Ag electrodes is found to be dependent upon both the large scale and atomic scale roughness of the electrode surface. The controlled surface morphology is generated by a double potential step ORC technique. Scanning electron microscopy of these surfaces reveals varying large scale surface morphologies that are dependent upon ORC rate. A correlation between SERS intensity and large scale surface morphology is interpreted in terms of significant contributions from electromagnetic effects in electrochemical SERS. The correlation between SERS intensity and this surface morphology is found to be independent of the presence of atomic scale roughness. The results presented here confirm and extend the results of previous investigations of the morphology of SERS-active surfaces.
