Csi afterglow
WebFinally, we find a substantial afterglow for GAGG:Ce scintillators over a few hours; such an afterglow is only minimally observed in other scintillators such as CsI:Tl and Bi4Ge3O12 (BGO). WebThe samples show good afterglow properties comparable with practical X-ray scintillators. The 1% and 3% Nd-doped LaMgAl11O19 samples show a good linearity in the dynamic range from 6–60,000 mGy ...

Single crystals of CsI, CsI:Tl, and CsI:Tl,Bi were grown by the vertical Bridgman method. We studied the effect of Bi 3+ codoping on the CsI:Tl X-ray-induced afterglow. Thermally stimulated luminescence measurements were carried out in order to investigate the role of traps. The results showed a remarkable reduction of …
