Abstract
Effect of activator concentration on luminescence spectra and luminescence decay of excited states of Tm3+ in indium-based fluoride glass has been investigated. Self-quenching of luminescence originating in the 1D2, 1G4 and the 3H4 levels is found to be significant at doping levels as low as 0.5%. Luminescence decay curves are consistent with the Inokuti-Hirayama model for the non-radiative energy transfer involving an electric dipole-electric dipole interaction. Critical distance R0=12.3 Å, derived from an analysis of the 1G4 decay, is relatively high and indicates that the glass matrix favours the ion-ion interaction. Relaxation dynamics for glass samples doubly doped with thulium and terbium provides evidence that terbium ions are able to shorten the 3F4 lifetime with extremely high efficiency. However, the Tm3+→Tb3+ energy transfer contributes adversely to relaxation of the 3H4 level. Critical distance for this interaction is nearly the same as that for the self-quenching of Tm3+ luminescence.
