Characterization and thermoluminescence behavior of beta irradiated NaBaBO 3 phosphor synthesized by combustion method

NaBaBO 3 host material was synthesized using the combustion method. In order to optimize the performance of the material, effects of sintering temperatures varying from 600° to 1000 °C were investigated. The sintering temperature and dwell time were found to have pronounced effects on the pure NaBaBO 3 material. X-ray powder diffraction (XRD) and scanning electron microscopy (SEM) techniques were used to confirm the phase formation and examine the surface morphology of the prepared powder material, respectively. TL behavior of NaBaBO 3 was studied at various beta doses. It is seen that the sample exhibits well resolved TL glow peak at a peak temperature about 175 °C and corresponding TL intensity increases with the increasing beta dose. However, TL glow peak slightly shifts to lower temperature with the increasing beta dose level. This is the first TL report of a phosphor with a NaBaBO 3 host. The TL kinetic parameters were estimated by the peak shape (PS) method and CGCD software. TL glow curves of NaBaBO 3 consist of several traps and exhibited second order kinetics. A possible TL mechanism was also discussed using the energy level model. The obtained results can provide valuable knowledge related to the investigation of the intrinsic nature characteristics of NaBaBO 3 in research fields pertaining to dosimetry. © 2018 Elsevier Ltd and Techna Group S.r.l.Firat University Scientific Research Projects Management Unit: FDK-2017-9622, FAY-2015-4735The authors are grateful for the financial support from the Scientific Research Projects of Cukurova University FDK-2017-9622 and FAY-2015-4735 projects
