    Abstract

    Spectroscopic and scintillation properties of BaY2F8 :Ce3+, BaLu2F8 and BaLu2F8 :Ce3+ are presented. For pure BaLu2F8, a luminescence with a decay time of similar to 1 ns is observed under gamma-ray excitation. This luminescence with a light yield of about 200 ph/MeV is attributed to core-valence luminescence. The scintillation efficiency of the Ce3+-doped crystals is rather poor and usually smaller than 1000 ph/MeV. The scintillation mechanism of these fluorides will be discussed.
