PbO-CaO-ZnO-B2O3 (PCZB) glasses of Dy3+ ions are prepared by conventional melt quenching technique and investigated by X-ray diffraction and Optical absorption spectroscopic techniques. The XRD spectra of the glass samples reveal an amorphous nature with different compositions within the glass matrix. The Optical absorption spectra of these glasses are recorded at room temperature. Nephelauxetic ratios, bonding parameters, Urbach energies, direct and indirect band gaps are calculated. Various significant physical properties (Density, Ion concentration, Inter-ionic separation and Polaron radius) of these glass samples have been evaluated.
