Abstract: Optical absorption and fluorescence spectra of Pr³⁺ doped borosilicate glasses of the composition (in wt.%) 68.94 SiO₂-22.55 Na₂O-1.91 CaO-4.96 K₂O -0.85 B₂O₃-0.29 As₂O₃-xPr₆O₁₁where x = 0.0, 0.2, 0.3 and 0.5 have been studied in UV-VIS/NIR regions. Judd-Ofelt theory has been applied to the f ↔ f transitions for evaluating various Ωλ (λ= 2, 4, 6) parameters. Using the fluorescence data and these Ωλ parameters, various radiative properties like spontaneous emission probability, branching ratio, radiative lifetime and stimulated emission cross-section of various emission lines have been evaluated. The values of these parameters have been used to predict potential laser transitions. The bonding environment surrounding the rare earth ion in this glass-network has also been discussed.
