Abstract: | Ag nanostructures on TiO2 films were deposited by RF magnetron sputtering under variable deposition parameters, such as DC potential, RF-power and total pressure. The concentration, shape, and distribution of the deposited nanostructures and continuous Ag films on thin films of TiO2 can be tailored by careful variation of the deposition parameters. Controllable clusterlike, islandlike and film Ag structures on TiO2 film were obtained, respectively. DC potential was found as an appropriate parameter to tailor the change of Ag nanostructure and the overall Ag amount. The compositions, nanostructures and morphologies of nanocomposite films appreciably influence the optical response. |
