Optical absorption and fluorescence spectra of Pr3+ doped bismuth borate glasses having glass system (60-x)B2O3-10Bi2O3-20Li2O-10ZnO-xPr6O11 where x=1, 1.5 and 2 mol% have been recorded. Judd-Ofelt theory have been applied to compute oscillator strength and intensity parameters Ωλ (λ=2, 4 and 6).  These parameters have been used to calculate the radiative properties of glasses viz., spontaneous emission probability (A), radiative life time (tR), fluorescence branching ratio (βR) and stimulated emission cross section (σp) of various emission lines have been evaluated. The results obtained suggest that these new materials can be considered as an interesting candidate for laser applications.
