Abstract：
The spectra and the decay times of a series of Ce³⁺-doped BaF₂ crystals have been measured. The results demonstrate that a BaF₂ with a proper amount of Ce³⁺ doped have outstanding advantages:the emission spectra shift from LTV band towards blue band, a near blue fluorescence with quite fast decay time (80 ns) replaces the slow component (~600 ns) and very fast one (~0.8 ns) of undoped BaF₂. The intensity of the new component is comparable with the sum of the odd ones.
