Abstract : ZnF2-TeO2 glasses mixed with the three different modifier oxides viz., ZnO, CdO and PbO doped with Pr2O3
were prepared. The glasses were characterized by X-ray diffraction, differential scanning calorimetry and IR spectra. Optical
absorption and fluorescence spectra of these glasses have been studied. From the measured intensities of various absorption
bands of these glasses the Judd-Ofelt parameters 2, 4, and 6 have been evaluated and compared with those of other
reported glass systems. From this theory various radiative properties like transition probability A, branching ratio
r, the
radiative life time R, and the emission cross-section E for various emission levels of these glasses have been determined
and reported. An attempt has also been made to throw some light on the relationship between the structural modifications
and luminescence efficiencies of all the three glasses.
