Abstract
Since the first observations of surface-enhanced Raman scattering (SERS) by molecules adsorbed on silver surfaces it has been recognized that the intensity of Raman scattering is strongly dependent on the state of division of the metal surface. The early experiments and much of the subsequent work on SERS has been carried out on silver electrodes randomly roughened by an electrochemical oxidation-reduction cycle in aqueous electrolyte. Such optimally roughened surfaces give particularly large SERS signals, and are therefore ideal for investigations into the adsorbate chemistry of silver electrodes. However, they are less favorable for probing the physics of enhanced Raman scattering, since it is difficult to measure some of their other optical properties, particularly their absorption spectra, and to account for these properties in terms of the roughness in a precise way. Much attention has therefore also been directed to more regular finely divided metal surfaces, viz. colloidal dispersions or evaporated island films, or the surfaces of diffraction gratings, all of which also exhibit SER scattering. This chapter discusses the experimental features of SER scattering by molecules adsorbed on aqueous silver and gold colloids.
