Luminescence performance of zinc phosphate glasses containing Eu{sup 3+} ion with the chemical compositions (60-x)NH{sub 4}H{sub 2}PO{sub 4}-20ZnO-10BaF{sub 2}-10NaF-x Eu{sub 2}O{sub 3} (where x = 0.2, 0.5, 1.0 and 1.5 mol%) has been studied. The Fourier Transform Infrared Spectroscopy (FT-IR) shows several vibrations bands. Luminescence spectra of these glasses exhibit characteristic emission of Eu{sup 3+} ion with an intense and most prominent red emission (614 nm) which is attributed to {sup 5}D{sub 0}→{sup 7}F{sub 2} transition. Judd-Ofelt (Ω{sub 2}, Ω{sub 4}) parameters have been evaluated from the luminescence intensity ratios of {sup 5}D{sub 0}→{sup 7}F{sub J} (where J = 2 and 4) to {sup 5}D{sub 0}→{sup 7}F{sub 1} transition as well as absorption spectra under different constraints. Using J-O parameters and excitation spectra, the radiative parameters are calculated for different Eu{sup 3+} doped glasses.
