Growth and scintillation properties of Eu doped BaCl2/LiF eutectic scintillator

Eu doped BaCl2/LiF eutectics were grown by the micro-pulling down method and their directionally solidified eutectic (DSE) system has been investigated. The grown eutectic showed main phases of cubic LiF and orthorhombic BaCl2. In these eutectics, the 399nm emission of Eu2+ 4f5d was obtained. It sho...

More Information
Summary:Eu doped BaCl2/LiF eutectics were grown by the micro-pulling down method and their directionally solidified eutectic (DSE) system has been investigated. The grown eutectic showed main phases of cubic LiF and orthorhombic BaCl2. In these eutectics, the 399nm emission of Eu2+ 4f5d was obtained. It shows the intrinsic decay time of about 410ns. The light yield of the 1-mm-thick eutectic showed 7000ph/5.5MeV alpha-ray.
