| roke-width: 0px; "> Lithium zinc phosphate glasses of the composition x Li2O – (45 – x) ZnO – 55 P2O5 (where 0 ≤ X ≤ 45 mole %) were prepared by the normal melt quenching method. Normally the structural characterization of amorphous materials are extracted from the analysis of glass density, (ρ), differential thermal analysis, DTA, optical, UV–Vis, infrared spectra, IR, and electrical conductivity,σdc . In the present studies all the above mentioned techniques are described, measured and analyzed. The systematic change in the variety of the present studied is explained by changes in the nature of the oxygen bonds in glass network due to the substitution of ZnO by Li2O in this glass system, which may be explained by different structural cross–linking of phosphate network with increasing Li2O mole% content. All the obtained optical parameters (Eopt, λcutoff, and ΔE) are found to be sensitive to the change of Li2O concentrations. The electrical conductivity σdc and its activation energy Eg showed a compositional dependence. The structural changes of the present glass system are confirmed by analysis the observed infrared spectra. The obtained values for all the studied properties show two compositional regions, first compositional region (0.0 -15 mole % Li2O content) and the second one (15 -45 mole % Li2O content). | ||||
