α-Al2O3:C crystal was grown by edge-defined film-fed grown technique (EFG) using high-purity graphite powder as carbon source. The thermoluminescence (TL) and optically stimulated luminescence properties(OSL) of low doses of β were investigated. The crystal shows three TL peaks at near 350, 540 and 689 K after irradiation with a β-rays source: the peak at near 540 K is the main TL peak, and the peak at near 689 K is the new TL peak. The depth of trap level of crystal has changes and produce trap level of new depth; the TL intensity increased with the irradiation doses, but no change is found in the position of TL peak. As the times of irradiation increase in the process of many consecutive irradiation of the same dose, the main TL peak intensity increases and the peak temperature shift to the direction of high temperature. The OSL decay curve of α-Al2O3:C crystal consists of the early-fast component and the late-slow component. With the increasing irradiation dose, the decay rate of the early-fast component changes slightly while that of the late-slow component decreased obviously. The TL and OSL dose response of the crystal shows excellent linear characteristic in the low dose range.Cited
