| Abstract: | The relation between the content of YF3 and oxygen in the host lattice and lumi-nescence change of Eu2 in BaF2-xYF3 has been studied. The energy transfer frotn Eu2 toTb3 in Ti-doped BaYF, was observed. The emission strength of Eu2 was found to be re-duced greatly and the decay time of the luminescence of the luminescence of Eu2 was shortened due to the energytransfer from Eu2 to Tb3 . |
