Description
Summary:A new series of Pr3+ doped phosphate glass with composition (5-x)P2O3.40Li2O.55B2O3.xPr2O3(x=0, 0.3, 0.5, 0.7) was prepared by melt quenching technique. XRD pattern of the prepared glass samples confirms the amorphous nature of glasses. The physical and optical parameters like density, Interatomic separation, molar volume, molar refraction, and refractive index are also studied. The density of the glasses increases while their molar volume values decrease with the increase of Pr3+ rare earth ion-doped phosphate glasses. The refractive index and dielectric constant of prepared glass increase with the increase in the doping concentration of Pr3+ rare earth ions in the glass samples. Electronic polarizability and optical basicity both increase with a doping concentration of Pr3+ rare earth ion. The metallization parameter values of the present glasses are found to be less than one and thus they exhibit insulating behaviour.
