Abstract
We reported a novel and versatile processing for the synthesis of Ag-carbon nanocomposites using the combination of the sputtering and PECVD techniques. The influence of the thermal annealing on the surface morphology, the structure and the optical properties of these films was studied. The effective medium model was used to describe the spectrophotometric measurements. Numerical calculations were allowed determining optical constants. The calculated transition gap Eg was found to vary between 1 and 1.5 eV depending on the annealing temperature. These values are lower than those reported for standard Ag-TiO2 and Ag-ZnO nanocomposites, which is promising for advanced optoelectronic devices.
