Abstract : Time-resolved stimulated luminescence is a method that is employ for the study of dosimetric materials including quartz, feldspar, carbon doped aluminium oxide, important materials used in dosimetry. Time-resolved OSL separate in time the stimulation and emission of luminescence. The dependence of luminescence intensity on measurement temperature was investigated using a newly designed LEDs based pulsing system. The intensity of the luminescence obtained decreases as the measurement temperature increases from 200C to 2000C for quartz annealed at 5000C and irradiated to 85 Gy. The luminescence intensity increases as the temperature was decreased from 200 to 20 0C. A similar trend was observed in both cases for change in intensity with respect to measurement temperature. The change in intensity against measurement temperature is as result of thermal quenching. The thermal energy of thermal quenching ΔE obtained was 0.62 ± 0.08 eV from 20 0C to 200 0C and ΔE = 0.67 ± 0.08 eV from 2000C to 200C in steps of 200C.
