Effect of Addition TiO₂ on Bi₂O₃-TiO₂-B₂O₃ Glasses

Abstract:

Bismuth titanium borate glasses in compositions xTiO₂ : (30-x)Bi₂O₃ : 70B₂O₃ (with x is in mol%, varying from 0% to 10%) were fabricated by the conventional melt quenching technique. The effect of TiO₂ on the physical and spectroscopic properties of bismuth borate glasses have been carried out by means of density and UV-Visible spectroscopy measurement techniques. The density and molar volume of all glasses are found to change depend on TiO₂ substitution. The fundamental absorption edges for all glasses have been identified using the theory proposed by Davis and Mott. The optical band gap (E_g) is found to decrease with increase in TiO₂ content.
