Abstract

The effect of zinc oxide on the structural, physical and optical properties of bismuth borate glasses system has been investigated by means of infrared and optical absorption spectroscopic techniques. The samples were prepared by normal melt-quench technique. The formation of tetrahedral coordination of Zn (i.e. ZnO 4) is not observed in glasses under study. The fundamental absorption edge for all the glass samples has been identified using the theory proposed by Davis and Mott. The optical band gap is found to increase with increase in ZnO content. The theoretical optical basicity has been reported as a function of Bi 2O 3. The density and molar volume of the present glass system are found to depend on ZnO substitution..
