The Effect of Xe Underlayers on the Surface Enhanced Raman Scattering of Pyridine on Cold Silver.

Abstract

Recently it has been proposed based on thermal desorption, electron spectroscopy and work function measurements that extremely small pores and cavities in silver films deposited at temperatures below 150K are the location of active sites for surface enhanced Raman scattering. The experiment reported here is an attempt to demonstrate in a more direct way that these cavities are responsible for the observed enhanced Raman scattering. It is shown that by filling these cavities with Xe atoms the enhancement effect on deposited pyridine can be dramatically reduced. Originator furnished keywords: Raman scattering, Surface, Enhanced, UHV, Silver.
