Abstract
In the present paper Na3SO4Cl:Ce, Na3SO4Cl:Dy, Na3SO4Cl:Mn, of Na3SO4Cl:Ce, Dy and Na3SO4Cl:Ce, Mn phosphor were synthesized by the wet chemical method. Thermoluminescence (TL) characteristics of Na3SO4Cl:Ce, Na3SO4Cl:Dy, Na3SO4Cl:Mn, Na3SO4Cl:Ce, Dy and Na3SO4Cl:Ce, Mn phosphors were studied for 5 Gy γ-ray dose. In TL glow curve, two peaks have been observed at 129°C and 224°C for different concentrations of Ce and Dy, whereas Mn peaks at 212°C. The same host is also tried for Ce, Dy (peaks at 126, 219) and Ce, Mn (248°C). A significant single peak is observed in the case of Na3SO4Cl:Mn and Na3SO4Cl:Ce, Mn. This may be due to the effect of activators. It is found that intensity tends to be increase with increased concentrations of the activators. The TL glow curves of the phosphors have been recorded and irradiated at a rate of 0.39 kGy h−1 for 5 Gy γ-rays dose. It is also found that all the phosphors are less sensitive as compared with Thermoluminescence dosimetry-CaSO4: Dy for the same γ-rays dose. The paper discuses the preliminary TL characteristics and effect of γ-rays on Na3SO4Cl:Ce, Na3SO4Cl:Dy, Na3SO4Cl:Mn, Na3SO4Cl:Ce, Dy and Na3SO4Cl:Ce, Mn phosphors.
