摘要：
The luminescence kinetics of CsI(Tl) exposed to an electron pulse irradiation (E(e) = 250 key, t(1/2) = 10 ns, j = 2 divided by 160 mJ/cm(2)) has been studied. It has been discovered that the slow emission rise is due to hole V(k)-Tl(0) recombination luminescence at temperature from 100 to 160 K and electron-V(kA) recombination, where electrons released from single Tl(0) at temperature from 180 to 300 K. The effect of Tl concentration on both processes has been investigated. (C) 2009 Elsevier Ltd. All rights reserved.
