摘要

xV _2O _5-xCeO _2-(30-x)PbO-(70-x) B _2O _3 glasses are synthesized by using the melt quench technique. The number of studies such as XRD, density, molar volume, optical band gap, refractive index and FTIR spectroscopy are employed to characterize the glasses. The band gap decreases from 2.20 to 1.78 eV and density increases from 3.49 to 4.25 g/cm ~3. FTIR spectroscopy reveals that incorporation of V _2O _5 in glass network helps to convert the structural units of [BO _3] into [BO _4]. At higher concentration of vanadium, VO vibration of [VO _5] structural units and V-O-V vibration are present. The bond ionicity of glasses increases with incorporation of V _2O _5 contents.
