Spectroscopic ellipsometry was used to determine the effective refractive index (n=n+ik). When the Ag volume fraction is over 2%, the linear optical properties of the nanocomposite films differ from those of the pure dielectric host. The extinction coefficient shows a maximum around 435 nm that is related to the surface plasmon resonance. Near this wavelength, the real part of the refractive index undergoes anomalous dispersion, leading to a significant increase of the n value of the composite compared to that of the matrixThis work has been partially supported by TIC99-0866, CICYT (Spain) and by the E.U. under the BRITE Project No. BRPR-CT98-0616.Peer reviewedAmerican Institute of Physics201220122001info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501http://hdl.handle.net/10261/45778reponame:DIGITAL.CSIC.
