Abstract
In this work, we synthesized the Dy doped BaF2 phosphor by co-precipitation method and studied its kinetic parameters. The synthesized BaF2:Dy was found to possess FCC structure and having an average crystallite size around 52 nmas obtained from XRD. BaF2:Dy was irradiated with 6MeV electron using Microtron Accelerator. The optimized TL result shows a single glow peak at 155 °C. Peak shape and Glow Curve Deconvolution (GCD) method has been usedto study the activation energy. Using the GCD method, we found better kinetics parameters than peak shape method when we compared it with experimental data. In GCD, we resolved TL glow curve into two peaks. The GCD results indicates that parameters for 1st peak and 2nd peak are E=0.9eV, b=1.8, s=6.27×1011 s−1 and E=1eV, b=1.09, s=3.4×1012s−1 respectively. BaF2:Dy shows a linear response over a wide range of radiation doses.
