摘要: Abstract The influence of annealing temperatures and different crystallite size the thermoluminescence (TL) properties SrSO4:Dy,Tb nanophosphor was studied. phosphor prepared by co-precipitation method. structural characterizations were analyzed XRD, composition investigated EDX morphology determined SEM technique. structure nanocrystalline powders an orthorhombic with average grain sizes 52, 57, 70 113 nm for 600, 700, 900, 1000 °C temperatures, respectively. energy absorption values calculated reflectance spectra results showed that affected numbers which appeared. approximately increased increasing temperature. In range 10 Gy–12 kGy, a linear TL dose-response related to peak maximum intensity observed. effect heating rate 2 5 °C/s in glow curve have been studied, too. analysis temperature on curves studied using computerized deconvolution (CGCD) activation between 0.5 3.45 form factor 900 °C 0.7 1.0 close EPR studies performed study defect centers sample.
