| 中文摘要 | intense tm3+ blue upconversion emission has been observed in tm3+-yb3+ codoped oxyfluoride tellurite glass under excitation with a diode laser at 976 nm. three emission bands centered at 475, 650 and 796 nm corresponding to the transitions (1)g(4) -> h-3(6), (1)g(4) -> h-3(4) and f-3(4) -> h-3(6), respectively, simultaneously occur. the dependence of upconversion intensities on tm3+ ions concentration and excitation power are investigated. for fixed yb2o3 concentrations of 5.0 mol%, the maximum upconversion intensity was obtained with tm2o3 concentration of about 0.1 mol%. the blue upconversion luminescence lifetimes of the tm3+ transitions (1)g(4) -> h-3(6) are measured. the results are evaluated by the possible upconversion mechanisms. |
