Abstract

The optical transmission spectra in a wide range of wavenumbers: infrared (IR), visible and ultra-violet (UV) regions have been measured for lithium borate glasses of compositions xCuO:(3 − x)V2O5:37Li2O:60B2O3 mol% (where x = 0.0–0.5). From the IR analysis, it was found that the different borate structural groups in these glasses are not affected by substitution of V2O5 by small quantities of CuO. The UV visible results are analyzed with the aim of determining the optical energy gap, Eopt, and the width of the localized states in the band gap. The values for Eopt are found to decrease as CuO content increases. Substitution of V2O5 by CuO creates additional localized states, due to Cu+2, overlapping with that due to the matrix and extended to the mobility gap.
