| 中文摘要 | a series of five different concentration erbium-doped tellurite glasses with various hydroxl groups were prepared. infrared spectra of glasses were measured. in order to estimate the exact content of oh- groups in samples, various absorption coefficients of the oh- vibration band were analyzed under the different oxygen bubbling times. the absorption spectra of the glasses were measured, and the judd-ofelt intensity parameters omega(i) of samples with the different erbium ions concentration and oh- contents were calculated on the basis of the judd-ofelt theory. the peak stimulated emission cross-section of (i13/2 ->i15/2)-i-4-i-4 transition of the samples was finally calculated by using the mccumber theory. the fluorescence spectra of er3+:i-4(13/2)->i-4(15/2) transition and the lifetime of er3+:i-4(13/2) level of the samples were measured. the effects of oh- groups on the spectroscopic properties of er3+ doped samples with the different concentrations were discussed. the results showed that the oh- groups had great influences on the er3+ lifetime and the fluorescence peak intensity. the oh- group is a main influence factor of fluorescence quenching when the doping concentration of er2o3 is smaller than 1.0 mol%, but higher after this concentration, the energy transfer of er3+ ions turns into the main function of the fluorescence quenching. and basically, there is no influence on the other spectroscopic properties (fwhm, absorption spectra, peak stimulated emission cross section, etc.). |
