| 英文摘要 | a modified fluoride glass with high tg (453 degrees c) and tx(onset)-tg(138 degrees c) value was studied as the er3+:nd3+ codoped 2.7 mu m gain media. interestingly, nd3+: 1600 nm absorption band that never been reported in glass material was observed. this band induces efficient non-phonon-assisted de-sensitization process in er3+: 2.7 mu m emission. surprisingly, a strong 817 nm peak was detected, which is proved to be induced by the cross-relaxation process based on the nd3+:i-4(15/2) level, making the energy back-transfer from nd3+ to er3+ possible. results show that nd3+ strengthens the er3+: 2.7 mu m emission significantly, but energy transfer coefficient from er3+ to nd3+ increases greatly with nd3+ enhancement, leading to more complicated inter-ionic interactions and more energy loss. low nd3+:er3+ ratio is preferred to achieve strong 2.7 mu m emission, meanwhile, suppressing upconversion luminescence, weakening the nd3+ interactions and decreasing the thermal load of 2.7 mu m lasing effectively.
