Relationship between surface-enhanced Raman scattering and the dielectric properties of aggregated silver films.
By using an evaporated silver film that has a continuously varying thickness, we have demonstrated the dependence of surface-enhanced Raman scattering (SERS) on the dielectric properties of the film. These results support local field models that are based on metal-particle resonances for SERS.
