Ce:YAG crystal

Cerium doped yttrium aluminum garnet (Ce:YAG) is kinds of scintillators with high light yield (9000Ph/MeV)and fast decay time (65ns), the luminescence peak locates at 550nm, which can effectively coupling with silicon photodiode detector devices. Besides, Ce:YAG crystals have the advantages of good physical and chemical properties, which make it the good material especially for middle-low energy ray detecting.
