Pr3+、Tb3+共掺的NaGdF4和GdB3O6的VUV荧光性质
Luminescent Properties of NaGdF4 and GdB3O6 Co-doped with Pr3+ and Tb3+ under VUV Excitation
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。
Abstract
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.
