Abstract: Several researchers have utilized physical treatments such a annealing temperature, annealing duration, ionizing radiation, grain size and optical bleaching as well as temperature of optical stimulation to establish the definite correlation between TL/OSL sensitivity and colour center with a view to suggest most appropriate physical treatment to be given to the specimen. The effect of temperature of optical stimulation (stimulation at room temperature (RT) (25°C) and stimulation at 160°C) on TL sensitivity, stability of TL peak and role of colour center for specimen annealed at 600°C and 1000°C followed by various beta doses has been studied in the present paper. The TL dose response curves were also plotted for each annealed sample after completion of optical stimulation. The present work reports that the 210°C TL peak is predominant for the specimens annealed at 1000°C prior to optical stimulation at room temperature. This peak remains thermally stable at 210°C and grows with dose systematically regardless of temperature of optical stimulation. The TL peak at 375°C is found to be intense, when the optical stimulation was performed at room temperature or elevated temperature of 160°C. The changes in TL glow curve pattern and sensitivity are strongly attributed to the role of E1’ center and Ge enter.
