摘要: Thermoluminescence (TL) properties of sulfate-based phosphors activated by different rare earths have received tremendous attention to the field radiation dosimetry. Those TL materials based on CaSO4 been widely applied for medical and environmental Taking this fact into account we synthesized Na6Mg(SO4)4 doped with Ce Tb wet chemical method. The prepared phosphor was characterized XRD, FTIR, photoluminescence (PL) thermoluminescence. For study, is irradiated g-rays from 60 Co source. studying luminescence properties, annealed at temperatures effects these annealing samples are investigated quantified. changes in glow curve PL emission spectrum also as a function temperature optimized. calculation trapping parameters various methods such peak shape (PS) method, initial rise (IR) heating rate (VHR) computerized deconvolution (CGCD) employed.
