چکیده انگلیسی
MgSO4:Dy phosphor was synthesized by solid state method. Sample characterization was carried out using X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS). Highest thermoluminescence (TL) sensitivity was observed at 0.3Â mol% of dysprosium impurity. Tm-TStop method was used to identify the number of glow peaks enclosed in TL glow curve. Computerized glow curve deconvolution (CGCD), initial rise and variable heating rate methods were used to determine kinetic parameters. TL sensitivity of produced MgSO4:Dy phosphor is approximately 8.5 times more than LiF:Mg,Ti (TLD-100). Other dosimetry features of the synthesized phosphor are presented and discussed.
