Thermoluminescence glow curve analysis and kinetic parameters of Dy-doped BaSi2O5 phosphor
文献摘要：
In this paper,Dy3+ incorporated BaSi2O5 phosphors were synthesized by gel combustion method and char-acterized by X-ray diffraction (XRD).The effects of various heating rates on thermoluminescence (TL) kinetics and glow peak temperatures of Dy3+ incorporated BaSi2O5 phosphors exposed to β irradiation at room temperature were investigated.The glow curves of the phosphor exposed to β-irradiation (0.1-100 Gy)consist of four main peaks located at 87,130,271,and 327 ℃ and exhibit a good linearity between 0.1 and 100 Gy.Three experimental techniques including variable heating rate (VHR),repeated initial rise (RIR),peak shape (PS) and computerized glow curve deconvolution (CGCD) were employed to determine TL kinetic parameters.Our findings indicate that the TL glow peaks of the phosphor obey first-order kinetics.Analysis of the main dosimetric peaks through the techniques mentioned above indicates that activation energies (E) and pre-exponential factor (s) are in the range of 0.80-1.50 eV and 1.15 × 108-3.28 × 1013 s-1.Additionally,it is found that the temperature of the glow peaks shifts toward the higher temperatures and the TL intensity smoothly decreases as the heating rate increases.The effect on the TL intensities and glow peak temperatures of the heating rate is discussed in terms of thermal quenching.
