Csi afterglow

WebThe one property of CsI (Tl) that limits its use in fast or time resolved applications is its afterglow. This causes problems in high count-rate applications, reconstruction artifacts … WebAug 16, 2024 · Here, we find that a temperature increase of only 60°, without changing the pulselength, cuts the afterglow of standard CsI:Tl films by a factor of 20. However, films of codoped CsI:Tl,Sm, whose afterglow has already been suppressed by the presence of Sm 2+ , show much less change as a function of either temperature or pulse duration.
