Luminescence and evaluation of trapping parameters in NaMgSO4Cl: X (X=Cu or Ce) phosphor

► The thermoluminescence (TL) characteristics of recently developed high sensitive mixed halosulphate phosphors, NaMgSO4Cl: Cu and NaMgSO4Cl: Ce were studied in comparison with CaSO4: Dy. ► In order to assess the possibility of their use in personal monitoring and TLD phosphors at very low dose of 5 Gy. ► It was found that NaMgSO4Cl: Cu is 5.59 times and NaMgSO4Cl: Ce is 6.18 times more sensitive as compared to standard CaSO4: Dy.
