Abstract

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 ⁴G_5/2 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.
