Abstract

NaGdF

and GdB

doped with Pr

and/or Tb

were prepared and their VUV excited fluorescence properties were studied. Gd

plays an important role in the energy transfer process from Pr

to Tb

upon the excitation of VUV photons. No obvious energy transfer from Pr

to Tb

was observed in the absence of Gd

; on the contrary

transfer most of the energy to Gd

after Gd

was added

then the energy was transferred from Gd

to Tb

. So the conversion from the near ultraviolet emission of Pr

to the green emission of Tb

was realized.
