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
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.关键词
