SreenivasuluAbstractVanadium ion doped zinc lead lithium phosphate glass samples are prepared by melt quench method. X-ray diffraction studies confirmed the amorphous nature of all the prepared glasses. The density and refractive index values of these glasses are evaluated using the Archimedes method and Abbe’s refractometer respectively. The values of density found to be in between 3.6363 and 3.6666 g/cm3. The refractive index values are observed in the range 1.5605–1.5620. An increasing trend has been observed in density and refractive index from the simultaneous variation of Li2CO3 and V2O5 in the host matrix. Optical absorption spectra of these samples exhibited two absorption bands at 548 and 738 nm which indicate the characteristic absorption peaks of V4+ ions. The optical basicity values of the studied glasses V1–V5 are identified to slightly vary from 0.6736 to 0.6718, which represents electron donor ability of oxide ions to the cations. The knowledge on optical basicity finds immediate applications in the design of the novel optical functional materials like polarizers, detectors and modulators with higher optical performance. The morphological variations have been observed in the studied glasses upon doping of V2O5 by using Scanning Electron Microscopy.
