Surface Enhanced Spectroscopy.
Abstract
We review the physical processes occurring when solid surfaces are used to modify in a substantial way the spectroscopic properties of molecules located nearby. This is achieved by enhancement of the local laser field, increase in molecular emission, and decrease in excited state life-time. We survey the use of flat surfaces, gratings, attenuated total reflection prisms, surfaces with small and large random roughness, isolated spheres and ellipsoids, and interacting solid surfaces. The spectroscopic techniques surveyed are surface enhanced Raman, fluorescence, resonant Raman and absorption. The possibility of enhancing photochemical processes is also discussed. We have made an effort to present all these topics from an unifying point of view and to survey the experiments relevant to the concepts presented. The level of presentation is aimed at a non-expert or an experimentalist without extensive theoretical skills.
