Study of ZnO modified Lithium Borate Bismuth glasses

Quaternary glasses with composition (40-x) Li2O:30B2O3:30Bi2O3: x ZnO have been prepared with x varying from 0 to 6 mol%. The structural investigation of these glasses has been carried out by infrared (IR) absorption spectra. Addition of ZnO in the glass is favorable for the creation of BiO 6 units...

Description
Summary:Quaternary glasses with composition (40-x) Li2O:30B2O3:30Bi2O3: x ZnO have been prepared with x varying from 0 to 6 mol%. The structural investigation of these glasses has been carried out by infrared (IR) absorption spectra. Addition of ZnO in the glass is favorable for the creation of BiO 6 units on account of the substitution of B-O bond by Bi-O bond. Changes in density and molar volume in glasses have been studied. Molar volume reduces which is ascribed to the decrease in boron-boron spacing, d . Increment in cut off wave length and decrement in. optical band gap energy is observed in Optical absorption spectra with increase in ZnO on account of rise in Non-Bridging Oxygens Electronic polarizability and optical basicity was also studied.
