||
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.
Features
Virtually no afterglow emissions
Emission peaking at 550nm is well matched with CCD detectors
Reasonably fast with a decay time of 70ns
YAG(Ce)'s light yield increases linearly with the total energy of the electron beam, whereas the response of phosphors dramatically decreases.
Applications
CT
Particle accelerator
PET
SPECT
LED lighting
Laser lighting
