In order to characterize and explore their structural properties, we measured the density, refractive index of the glass which shows increasing trend with increase in Pr<sub>2</sub>O<sub>3</sub> concentration also FTIR and XRD spectrum is used to study the structural properties of the developed glasses. XRD shows amorphous structure of the prepared glasses. FTIR shows B-O stretching (BO<sub>3</sub>)<sup>-</sup> units and Symmetrical stretching vibration of Te-O in TeO<sub>4</sub>. The electronic states belonging to the 4<em>f</em> configuration of trivalent Pr<sup>3+</sup> were determined from the absorption spectra. Multiphonon decay rate (<em>W<sub>mp</sub></em>), electron-phonon coupling strength (g) and host dependent parameter (α) were measured for the present glasses. The excitation spectra of the Pr doped glass samples were monitored at 605nm. In the PL spectra, the characteristic emission bands due to  <em>f–f</em> transition of Pr<sup>3+</sup> were confirmed for the glass system, the highest transition <sup>3</sup>P<sub>0</sub> → <sup>3</sup>H<sub>4</sub> and <sup>1</sup>D<sub>2</sub> → <sup>3</sup>H<sub>4</sub> corresponding to 589nm and 605nm respectively shows increase in intensity at 0.1mol% concentration of Pr<sup>3+</sup>.</p>}, number={2}, journal={Journal of Metals, Materials and Minerals}, author={Rajaramakrishna, Rajaramakrishna and Wongdeeying, Chananya and Yasaka, Patarawagee and Limkitjaroenporn, Pruittipol and Sangwaranatee, Narong and Kaewkhao, Jakrapong}, year={2019}, month={Jan.} }
