Abstract

Rare earth doped oxyfluoroborate glasses have been prepared with different concentration of Eu3+. The UV-Vis/NIR optical absorption, laser induced fluorescence and photoacoustic spectra of Eu3+ in this host have been studied. Different optical parameters such as oscillator strength, Judd-Ofelt intensity parameter, stimulated emission cross-section, transition probability, branching ratio and radiative lifetime, etc. have been calculated. Lifetime of the 5D0 level at various concentrations of Eu3+ have been used to explain the concentration dependent fluorescence quenching. The mechanism of quenching was found to be dipole-dipole. Energy transfer have also been studied from Eu3+ to Pr3+ in sample with 1mol% Eu3+ + 1 mol% Pr3+.
