                                 Abstract:The spectra and decay times of a serious of Ce+3—doped BaF2 crystals have been determined.The results demonstrate that a BaF2 crystal with a proper amount of Ce+3 doped have some outstanding advantages:a near-blue fluorescence with quite fast decay time (80ns) replaces the slow component (600ns) and vary fast one (~0.8ns) of undoped BaF2.The intensity of the new component is comparable with the sum of the old ones.
