A Study Optical and Physical Properties of Soda Lime Silica Glass Doped with ZnO

Abstract

A new set of soda lime glasses doped with ZnO were prepared by melt quenching technique. The aim of this work is to investigate physical and optical properties of prepared glasses using Archimedes’ method, and UV-VIS-NIR spectrometer. The data were analyzed by Origin Graph Program (version 8.6). The results shows that the density of glasses increases in rang 2.486 ~ 2.5656g/cm3, with increasing of concentration of ZnO because of higher molecular weight of ZnO compared with SiO2. The molar volume of glasses decreases, in range 24.1255 ~ 23.4019 cm3/mol, with increasing of concentration of ZnO, this indicates that the structures of glasses more compacted with addition of ZnO. The refractive index and optical energy band gap of glasses change in range 1.314 ~ 1.504 and 3.049 ~ 3.253 eV respectively, because of change of non-bridging oxygen. The absorbance of UV-VIS rays shows that ZnO have a good effect on glass transparency.
