WebDec 14, 2024 · CsI(TI) is also hygroscopic and should not be subjected to high humidity or water. CsI(TI) has different decay times for different particles (680ns and 3340ns) and … WebSep 18, 2024 · CsI:Tl is used as a scintillator material. This is because it has high conversion efficiencies for X-ray, and its broad emission in range of 400–800 nm with a peak at 550 nm is sensitive to Si-based photodiodes [ 2, 8 ]. CsI:Tl is filled in holes on the silicon collimator for optical separation, and joined with a Si-based photodiode array.
