Description
Ce:YAG single crystal is a fast decay scintillation material with
excellent comprehensive performance, with high light output (20000
photons MeV), fast luminescent decay (~ 70ns), excellent thermal
mechanical properties, The peak wavelength of luminescence (540 nm)
matches well with the receiving sensitive wavelength of common
photomultiplier tube (PMT) and silicon photodiode (PD), good light
pulses distinguish between γ rays and α particles, Ce:YAG is
suitable for detecting light charged particles such as α particles,
electrons and βrays, Especially, the good mechanical properties of
Ce:YAG single crystal make it possible to fabricate thin screen
with thickness less than 30 um.. Ce:YAG scintillation detectors are
widely used in electron microscopy, β and X-ray counting,
electronic and X-ray imaging screens and other fields.
