Abstract
Ba2Mg(BO3)2:RE3+(RE = Dy, Tb or Tm) phosphors are synthesized by high-temperature solid-state reaction method and their thermoluminescence (TL) properties under the beta-ray irradiation were studied. Tm3+ is the most efficient activator in this system and its deconvoluted TL glow curve shows a main TL peak at about 160°C. The peak position of Tm3+-doped Ba2Mg(BO3)2 phosphor shifts to the high temperature with the increase of beta-ray irradiation dose and its beta-ray dose response was linear in the range from 0.115 to 0.952 Gy. Further, the kinetic parameters of Ba2Mg(BO3)2:Tm3+ were estimated by the peak shape method and the heating rate method, and the calculated average activation energies and the frequency factor were 0.98 eV, 3.31 × 1010 s−1 and 0.94 eV, 1.04 × 1010 s−1, respectively, highly consistent with each other.
