摘要：

The optical properties of Ag-TiO2 nanocermet thin films are studied with the aim of optical filtering applications. Beyond the classical properties of cermets with noble metal inclusions predicted by the effective medium theories, the optical properties of Ag-TiO2 nanocermets deposited by R.F. cosputtering are governed by their columnar morphology and the under-stoichiometry of the TiO2 matrix. A careful experimental analysis of the different parameters and effects involved in the optical response of these nanocermets is performed both on TiO2 and Ag-TiO2: film thickness, silver volume fraction, thermal treatments, oxidation. The influence of these parameters on the surface plasmon resonance and the infrared transmission of the nanocermet thin films is optimized.
