Abstract: The relation between the content of YF3 and oxygen in the host lattice and luminescence change of Eu2+ in BaF2-xYF3 has been studied. The energy transfer frotn BaF2-xYF3 to Tb3+ in Ti-doped BaYF3 was observed. The emission strength of Eu2+ was found to be reduced greatly and the decay time of the luminescence of the luminescence of Eu2+ was shortened due to the energy transfer from Eu2+ to Tb3+.
