Thermoluminescence of Sc2O3 exposed to beta-particle irradiation

Abstract In this work, the thermoluminescence (TL) features of Sc2O3 exposed to beta particle irradiation in the dose range from 0.08 to 150 Gy are reported. Characteristic glow curves exhibit two main TL maxima, located at 74 and 192 °C when a 2 °C/s heating rate is used. The TL response as a function of dose exhibits a linear behavior for doses below 70 Gy. We conclude that Sc2O3 is a promising phosphor material for using as TL dosimeter.
