Abstract： Three kinds of Er3-doped tellurite glasses with different hydroxyl groups are prepared by the conventional melt-quenching method. Infrared spectra are measured to estimate the exact content of OH- groups in samples. The maximum phonon energy in glasses are obtained by measuring the Raman scattering spectra. The strength parameters Ω5 (t=2,4,6) for all the samples are calculated and compared. The nonradiative decay rate of the Er3+4I13/2 → 4I15/2 transition are calculated for the glass samples with different phonon energy and OH- group contents. Finally, the effect of OH- groups on fluorescence decay rate of Er3+ is analysed, the constant KOH-Er of TWN, TZPL and TZL glasses are calculated to be 9.2×10-19cm4s-1, 5.9×10-19cm4s-1, and 3.5×10-19cm4s-1, respectively.
