摘要：PbO-P2O5-ZnO-V2O5 glasses composed of different alkali oxides are prepared. The glasses arecharacterized by XRD, FTIR, EPR and UV-Visible spectral analysis. The functions of structural features andamorphous nature due to compositional changes are examined using XRD. FTIR spectroscopy is used to identify thepresence of bond assignments and vibrational modes of phosphate in the system. Depolymerization of the phosphatenetwork by the replacement of alkali oxide content in the glasses which are consisting mainly more of (PO43-) and(PO32-) units, is detected by the FTIR spectra. The spectral studies have exhibited an intense and broadband in thevisible region which is related to VO2+ ions in a ligand field of C4v symmetry. The importance of bridging oxygen inimproving the optical properties is studied.
