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.
