Normal incidence transmittance and reflectance spectra of sputtered nanocomposite monolayer films of Ag in SiO 2 , buried and unburied, showed significant redshifted plasmon resonances from 410 to 455 nm , which could be well interpreted with a simple model that starts from the Maxwell Garnett theory and the Kreibig extension of the Drude–Lorentz equation, but with a further extension related to the dipolar interaction between the metal particles distributed on a surface.
