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 Eu²⁺ to Tb₃ in Ti-doped BaYF, 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 energytransfer from Eu²⁺ to Tb³⁺.
