| 英文摘要 | Er3+ /yb3+ gd3sc2ga3o12 and er3+ : gd3sc2ga3o12 crystals have been grown by czoehralski method. the absorption spectra from 320 to 1700 nm and the up-conversion fluorescence spectra from 500 to 750 nm of them were investigated at room temperature, respectively. the possible up-conversion luminescence mechanisms in er3+ /yb3+ -codoped crystals and their influences on the 2. 8 mu m laser emission were discussed. experimental results show that the absorption of er3+: gd3sc2ga3o12 around 966 nm and its bandwidth are remarkably increased by yb3+ sensitizing. under 940 run excitation, the up-conversion luminescence intensity of er3+ /yb3+ : gd3sc2ga3o12 is much stronger than that of er3+ : gd3sc2ga3o12. it demonstrates that there exist effective energy transfer processes between yb3+ and er3+ and the dominant mechanism of up-conversion may be the energy transfer processes of yb3+ -er3+ and er3+ - er3+. |
