Ce YAG Scintillation Detector
Description
Cerium doped yttrium-aluminum garnet (Ce:YAG) is a well established scintillator and has many attractive properties, such as fast decay (60~70ns), high light yield, emission peaks at 520-550nm that well matched with the sensitivity of commercial Si-CCD detectors as well as good mechanical and chemical stability. The Ce:YAG is also a very appropriate crystal for imaging screens, LED lighting and laser lighting.
