The Study of Method Preparing Golden Yellow Melted Glass and its Optical Performance

This paper presents the method of preparing a new golden yellow glass with relatively strong absorption of ultraviolet light. This golden yellow glass is to be produced from the glass raw material, Na2O-CaO-SiO2, as fundamental material with addition of cerium(IV) Oxide (CeO2) and titanium(IV) Oxide (TiO2) in combination as colorants.The analysis of spectrum transmittance and chroma Index have been carried out on the plates of this golden yellow glass by light dispersion equipment CARY500. Results indicate that the optical performance and chorma index of this new Golden Yellow melted Glass are largely depended on the factors such as concentration of colorants , oxidizability – reducibility of mixed batch and addition of fluorite.

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

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 Na2O, 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.
