Résumé / Abstract

Nano silver oxide thin films have shown plasmon assisted fluorescence phenomenon which can be used for optical data storage. In the present report, we present the results of fluorescence of nano silver thin films prepared by DC Magnetron sputtering technique at low temperature (150K). The nano silver thin films are oxidised and are irradiated with blue light (A = 440 nm), a fluorescence emission is observed in the red region (A = 660 nm). These films are analysed by XRD and AFM. Emission spectrum was recorded using fluorescence spectrometer. Films of thicknesses 50A to 600 A are prepared and compared the fluorescence properties. It is observed that the fluorescence emission from the silver clusters depends on growth parameters in sputtering (like substrate temperature or deposition rate) and on the oxidation temperature.
