Calculated energy dependence of CaSO4:Dy TL phosphor and phosphor embedded Teflon for X and gamma rays

Influence of Li dopants on thermoluminescence spectra of CaSO4 doped with Dy or Tm

“…These sulphates are widely used for both individual and environmental radiation monitoring [1][2][3]. Their popularity has led to an extensive series of studies aimed at elucidating their behavior, attempting to assess the underlying mechanisms, and efforts to predict, or empirically develop new variants of these phosphors [4][5][6][7][8][9][10]. One particularly interesting result was reported by Dr Prokic who found that the addition of a lithium co-dopant during preparation of the CaSO 4 :Dy (or Tm) results in a major increase of luminescence efficiency.…”
