Spin-coated Ag (As0.33S0.67)100− films: preparation and structure

Abstract We report for the first time on the preparation of samples of Ag x (As 0.33 S 0.67 ) 100− x (from x =0 to 25 at.%) amorphous films by a standard spin-coating technique from n -butylamine solution of the glass constituents. Prepared films were stabilized by annealing in a vacuum furnace purged by inert argon atmosphere. The chemical composition of the spin-coated films has been established. Measurements of the chemical and physical properties of prepared films have been carried out using techniques such as UV/VIS/NIR spectroscopy to characterize the optical properties of films, FTIR and Raman spectroscopy to control the embedded organic solvent content in films and to determine the films structure.
