英文摘要	The use of Nd3+ codoping for sensitizing the Ho3+ ion and enhancing the similar to 3.9 mu m emission from Ho3+:I-5(5) -> I-5(6) was investigated in the PbF2 crystal for the first time, to the best of our knowledge. The similar to 3.9??mu m fluorescence emission properties and energy transfer mechanism of the as-grown crystals were investigated. The results show that the Nd3+ ion can act as a sensitizer to the Ho3+ ion, providing an efficient excitation channel, making the Ho3+/Nd3+:PbF2 crystal propitious to be pumped by commercialized InGaAs laser diodes (LDs). Moreover, an enhanced similar to 3.9 mu m emission was obtained in the Ho3+/Nd3+:PbF2 crystal due to the codoping of Nd3+ ions, leading to an efficient energy transfer from a lower laser level of Ho3+:I-5(5) to Nd3+:I-4(15/2), while having little influence on the higher laser level of Ho3+:I-5(5). These advantageous spectroscopic characteristics indicate that the Ho3+/Nd3+:PbF2 crystal might have potential application in similar to 3.9 mu m mid-infrared lasers under a conventional 808 nm LD pump.
