| Abstract | Glass composition (30-x)TeO2-30B2O3-10ZnO-30BaO-xPr2O3 x = 0.00, 0.05, 0.10, 0.50, 1.00, and 1.50 mol% were fabricated using conventional melt quenching technique. In order to explore their structural and luminescence behavior, we measured the density, refractive index of the glass which shows increasing trend with increase in Pr2O3 concentration, also FTIR and XRD spectrum were analyzed to study the structural properties of the developed glasses. XRD shows amorphous structure of the prepared glasses. FTIR shows B-O stretching (BO3)- units and symmetrical stretching vibration of Te-O in TeO4. The electronic states belonging to the 4f configuration of trivalent Pr3+ were determined from the absorption spectra. Multiphonon decay rate (Wmp), electron-phonon coupling strength (g) and host dependent parameter (?) were measured for the present glasses. The excitation spectra of the Pr doped glass samples were monitored at 605 nm. In the PL spectra, the characteristic emission bands due to ff transition of Pr3+ were confirmed for the glass system, the highest transition 3P0 ? 3H4 and 1D2 ? 3H4 corresponding to 589 nm and 605 nm respectively shows increase in intensity at 0.1 mol% concentration of Pr2O3. |
