Study on Thermoluminescence glow (TL) curves of X- irradiated BaSO₄: Dy phosphors

The BaSO₄: Dy phosphors for different concentrations of Dy have been prepared by simple chemical route. TL glow curves of the X-irradiated BaSO₄: Dy phosphors have been recorded at room temperature. The observed TL glow curves of the phosphors show two sharp peaks at Tm =(375–383) K and Tm = (433–437) K. Also, TL glow curves of BaSO₄: Dy phosphor at a particular concentration of Dy irradiated with different doses of X-rays have been recorded. And trapping parameters of the glow curves were evaluated by CGCD technique. The study of the dose-response curves of the phosphors at a particular dopant concentration shows that BaSO₄: Dy may be used as dosimeters.
