Abstract

BaxSr1-xSO4: Dya%, Tbb% nanoparticles were synthesized by the chemical co-precipitation method. The orthorhombic lattice structure was confirmed by X-ray diffraction (XRD) pattern and an average size of 63. 5nm was obtained using Deby-Schere`s formula. The shape and size of particles were also observed by scanning electron microscopy (SEM). EDX spectra proved the presence of Dy and Tb in the sample. The TL glow curves of samples showed the maximum sensitivity at 0. 12, 0. 88, 0. 5, and 1. 5 mol% for Sr, Ba, Dy, and Tb, respectively. The Thermoluminescence (TL) glow curves of the sample (in the range of 0. 05-100 mGy) had two glow peaks at 534 and 615 K. Dosimetry characteristics of the selective combination were studied. The best heat rate was 2 K/s. The TL intensity was increased by increasing the dose up to 7 kGy and after that, it was increased very slowly. Studies of the fading indicated that the reduction of dose-response of the sample in 1000 mGy dose is negligible within 21 days. Energy response was studied in the range of 80-1250 keV and showed the sample was energy-dependent.
