摘要：

The scintillation properties of powders and single-crystals of BaFI doped with Eu2+ are presented. Single crystals were grown by the vertical Bridgman technique. Under optical and X-ray excitation, the samples exhibit a narrow Eu2+ 5d-4f transition emission centered at 405 nm. The scintillation light output is estimated to be 55,000 +/- 5,000 photons/MeV at 662 keV with 85% of the light decaying within 600 ns. An energy resolution of 8.5% full width at half maximum (FWHM) has been achieved using this scintillator for 662 keV excitation (Cs-137 source) at room temperature.
