Abstract

Novel self-agglomerating Eu doped CaSO4 phosphors were synthesized by a cheap, easy, and environmental friendly chemical route. Pellet-shaped sintered samples were obtained without any binding material, and exposed to beta particle irradiation. The thermoluminescence (TL) response in the 0.08-2.6 Gy dose range increased linearly as the radiation dose increased. Glow curves exhibit the most intense maximum close to 200 {ring operator} C, and two much less intense maxima at 250 and 330 {ring operator} C when a 5 {ring operator} C / s heating rate is used. No TL peaks shift is observed when dose changes, which is characteristic of first order kinetics TL processes. The whole glow curve displays a remarkable stability under storage at room temperature. The main peak intensity is 2.5 times greater than that of the TLD-100. The method here reported can be used to synthesize CaSO4 with other dopants. © 2007 Elsevier Ltd. All rights reserved.
