XPS Studies on Light-Yellow Glass Prepared by Sol-Gel Dip-Coating

摘要

Light-yellow glass was prepared by coating silver film on the flat glass substrate surface with sol-gel dip-coating process. The chemical composition and the valence state of elements on the surface of silver thin film deposited on glass substrate were studied by X-ray photoelectron spectroscopy. Results show that: elements of Na, Mg, Ca exist in the form of their respective stable state, such as Na_2O, MgO, CaO, when heat treated at 500°C for 0.5h; but Si is unstable, and exhibit stoichiometrical disturbances. Results of chemical composition and their content by weight percent of silver thin film surface reveal that minute of quantity silver on the glass surface can lead to the glass with light-yellow color. The transmission of light for the light-yellow glass, deep-yellow glass and the flat glass substrate was also analyzed by spectrophotometer, and the results indicate that the light-yellow glass is capable of absorbing UV rays heavily.
