Physical and Optical Properties of Cuo Doped in Soda Lime Silicate Glasses Produced from Waste Glass Cullet

Abstract

AbstractFor this article, waste glass cullet obtained from the glass industry was used as a choice of SiO2 substitute in glass manufacturing. A series of soda lime silicate glasses doped with CuO, in composition (55−x) SiO2: 15Li2O: 20Na2O: 10CaO: xCuO (x = 0.00, 0.01, 0.02, 0.03, 0.04, and 0.05 mol%)) were prepared by melt-quenching technique. The parameters such as density and molar volume were measured and evaluated their oscillator strength, refractive index, ion concentration, polaron radius, and inter-nuclear distance. Optical properties such as refractive index, absorption spectra, optical band gab, and CIE L*a*b* were investigated. With increasing of CuO concentration, the density and the refractive index of glasses increased, while the molar volume decreased. The absorption spectra show board peak in the range of 550 to 950 nm. The addition of CuO generated the blue hue in glasses, corresponding to the CIE L*a*b color coordinate.Keywords: Waste glassculletsoda lime silicateglassCuO AcknowledgmentsThe research team would like to thank the Nakhon Pathom Rajabhat University Research Center of Excellence in Glass Technology and Materials Science for providing tools and equipment as well as facilitating research operations.Disclosure StatementNo potential conflict of interest was reported by the author(s).
