摘要：

The xY(2)O(3)center dot(60 - x)P2O5 center dot 40SiO(2) vitroceramic compounds exhibited excellent TL output following beta irradiation, especially when doped with high Y2O3 concentrations, as showed in a recent work conducted by Biro et al., 2015. In the first section of this paper, the previous recorded TL glow peaks were further analyzed and their corresponding kinetic parameters such as an order of kinetics (b), trap depth (E) and frequency factor (s) were determined using the Chen's peak shape method. In the second section, the thermoluminescence characteristics of SiO2-P2O3 doped with different Y2O3 concentrations were simulated using the TTOR (Two traps & one recombination center) model. All calculated TL glow curves were in good agreement with the experimental results. (C) 2016 Elsevier GmbH. All rights reserved.
