Scaling-induced enhancement of X-ray luminescence in CsI(Na) crystals [PDF]

, 2013
We report on the diameter dependence luminescence property of CsI(Na) crystals under X-ray excitation. When CsI(Na) crystal diameter decreases to nano-scale, the X-ray excited luminescence decay time is speeding up from similar to 600 ns to similar to 10
