Rare earth ion doped oxyfluoroborate glasses have been prepared with different concentration of Sm3+. The UV-Vis-NIR optical absorption, laser induced fluorescence and photoacoustic spectra of Sm3+ in this lattice have been studied. Optical parameters such as oscillator strength, stimulated emission cross-section, transition probability, radiative lifetime etc. have been calculated. Lifetime of the 4G5/2 level at various concentrations of Sm3+ have been used to explain the concentration dependent fluorescence quenching. The mechanism of quenching was found to involve quadrupole-quadrupole coupling.
