| 中文摘要 | y2o3:sm and gd2o3:sm powder phosphors were prepared by carbonate coprecipitation method. the purified crystalline phases of y2o3:sm and gd2o3:sm were obtained at 600degreesc, and the crystallinity increases with increase in annealing temperature. both samples contain aggregated phosphor particles. an energy transfer (et) from y2o3 and gd2o3 hosts to sm(3+) has been observed, and the et efficiency in the latter is higher than that in the former because an energy migration process like gd3+-(gd3+)(n)-sm3+ has occurred in the latter. furthermore, an upconversion luminescence from the (4)g(5/2) level of sm3+ has been observed in both y2o3 and gd2o3 under the excitation of 936 nm infrared, whose mechanisms are proposed. both the up and downconversion emission intensities of sm3+ in gd2o3 are stronger than those in y2o3. |
