Title: Study of lithium borate glasses containing Bi{sub 2}O{sub 3}

The effect of Bi{sub 2}O{sub 3} addition on the properties of 30Li{sub 2}O:(70−x)B{sub 2}O{sub 3}:xBi{sub 2}O{sub 3} (0≤x≤35 mol %) has been studied. Density and molar volume are increasing with Bi{sub 2}O{sub 3} content. The observed decrease in glass transition temperature and optical band gap has been explained on the basis of increase in non bridging oxygen which is supported by infrared spectroscopy. From the optical transmittance spectra it is observed that the cut off wavelength increases with Bi{sub 2}O{sub 3} content which is related to the structural changes.
