Abstract
Optically stimulated luminescence (OSL) of Lu2SiO5:Ce powder (Phosphor Technology Ltd., UK) has been measured by Risø TL/OSL Reader (TL-DA-15). Upon blue photon stimulation (λex ∼470 nm) the material shows strong OSL signal that can detect β-irradiation right up to the dose of ∼0.2 Gy.A brief discussion on this finding is presented by comparing the thermoluminescence of the system with and without optical stimulation. The two key important parameters namely, trap-depth (E) and frequency factor (s) of the main peaks that occur at 85 and 232 °C are determined.
