摘要：

A spectroscopic study has been performed in indium-based fluoride glasses doped with different Tm3+ concentrations (0.1, 0.5 and 2.5 mol%). The decay of the luminescence from the H-3(4), 1G4, 1D2 and I-1(6)-P-3(0) levels has been measured for every concentration of Tm3+. These decays are exponential for 0.1 mol% Tm3+. When the concentration is enlarged, the decay curves become non-exponential because of cross-relaxation and energy diffusion. The decays are analyzed in the frame of the Yokota-Tanimoto energy transfer formula in the range of temperature 10-300 K.
