中文摘要：

分别制备了单掺和双掺Pr3＋和Tb3＋的NaGdF4和GdB3O6等材料,研究了其真空紫外荧光性质。发现在VUV光的激发下,Gd3＋离子在Pr3＋和Tb3＋的能量传递过程中起着重要的作用。Gd3＋离子不存在时,Pr3＋和Tb3＋之间没有明显的能量传递过程。当体系中加入Gd3＋离子后,Pr3＋将大部分能量传递给中间体Gd3＋,Gd3＋再将能量传递给Tb3＋,实现了将Pr3＋的近紫外光转化为Tb3＋的绿色光的转换过程。

英文摘要：

NaGdF4 and GdB3O6 doped with Pr3＋ and/or Tb3＋ were prepared and their VUV excited fluorescence properties were studied.Gd3＋ plays an important role in the energy transfer process from Pr3＋ to Tb3＋ upon the excitation of VUV photons.No obvious energy transfer from Pr3＋ to Tb3＋ was observed in the absence of Gd3＋;on the contrary,Pr3＋ transfer most of the energy to Gd3＋ after Gd3＋ was added,then the energy was transferred from Gd3＋ to Tb3＋.So the conversion from the near ultraviolet emission of Pr3＋ to the green emission of Tb3＋ was realized.
