This paper presents the effect of TiO 2 addition on the physical and optical properties of TeO 2 -ZnO-Na 2 O glasses. For this study, glasses with the compositions of 63.16TeO 2 - (31.57-x) ZnO – 5.26 Na 2 O – xTiO 2 (where x = 1.06, 2.11, 3.16, and 4.22 mol%) were prepared with melt quenching technique. Glasses were characterized in order to obtained glass density, refractive index, and absorption spectra ranging from UV to IR regions. From these basic data, we have evaluated the values of molar volume, oxygen packed density, polaron radius, inter-ionic distance, field strength, and optical band gap. It was observed that incorporating TiO 2 into the glasses to substitute ZnO have resulted in decreasing the values of density, inter-ionic distance, and field strength; and yet increasing molar volume, oxygen packed density and polaron radius. The structural units building the glass networks have also been evaluated.
