| 英文摘要 | Er2+-doped tellurite glasses with four different concentrations were fabricated, and the oscillator strength of er3+ in the tellurite glasses were calculated through the absorption spectra of the glasses. the judd-ofelt intensity parameter omega(i), spontaneous transition probability a, fluorescence branching ratio beta and radiative lifetime tau(rad) of er3+ were calculated on the basis of judd-ofelt theory, and the effect of the erbium. ion concentration on the above optical parameters was also discussed. the fluorescence spectra of er3+:4i(13/2)->i-4(15/2) transition and the lifetime of er3+:i-4(13/2) level of the samples were measured. the stimulated emission cross-section of i-4(13/2)->i-4(15/2) transition of the samples was finally calculated by using mccumber theory. the results show that with the increase in the er3+ concentration, the oscillator strength and spontaneous transition probability a of er3+ increase, while the fluorescence branching ratio beta of er3+ shows little difference. the stimulated emission cross-section of er3+:i-4(13/2)->i-4(15/2) transition of the samples changes slightly with the increase in the er3+ concentration. all the fluorescence effective line widths for the four different er3+ concentration samples are nearly 50 nm. |
