N2 - Absorption and fluorescence spectra of Sn2+ and Sb3+ in borax, phosphate, and germanate glasses were measured in the temperature range 87-295°K. Fluorescence decay times of these ions in borax glass at 87°K was a single exponent with τ ≈ 6-11 μsec. At 293°K, two decay times were resolved in the range of 50-2000 nsec. The nonexponential behavior is interpreted by the repopulation of the 3P1 level from the 3P0 level. The temperature dependence of fluorescence and the low values of quantum efficiencies of fluorescence are explained by means of the configurational coordinate diagram model.
