Fluorescence Enhancement of Rhodamine 6G Molecules in TiO2 Semiconductor Colloid
Since the discovery of Surface-Enhanced Raman Scattering(1) much effort has been devoted to understanding the nature of the interaction of molecules with rough surfaces. Several theoretical models have been suggested to explain it(2). The authors turn special attention to the surface plasmon model(3). According to this model, the enhancement is due to the amplification of the incident and radiated optical fields by plasma resonances of the metal.
