Effect of TiO2 Addition on Optical Properties of TeO2-ZnO-PbO Glasses

Abstract

Abstract Glasses with composition (in mol%): 60TeO2-(30-x)ZnO-10PbO-xTiO2 (TZPb:Ti) (where x = 0, 1, 2, 3 and 4) have been fabricated and characterised in order to study their physical and optical properties. Density and refractive index of glasses were measured at room temperature by applying Archimedes’s principle and Brewster’s angle method, respectively. Absorption spectra within range of UV-VIS-NIR were measured at room temperature using UV-VIS Spectrophotometer while those at IR range using FTIR. We have shown that density decreases with the increase of TiO2 while refractive index and optical energy band gap behave conversely.
