Commercially available and indigenously developed single crystal α-Al 2 O 3 :C (using Post growth Thermal Impurification (PGTI) technique), were studied for their thermoluminescence (TL) response in the temperature range from -100 o C to 60 o C. Both types of samples were found to possess similar pattern of TL peaks. In PGTI samples, a dominant TL peak occurred at 8 o C and commercial reference samples showed an intense TL peak at 12.5 o C. The results indicate that the nature of shallow traps formed using PGTI method is qualitatively analogous to those created by conventional method of growing single crystal α-Al 2 O 3 :C in vacuum in graphite ambience. The low temperature TL peaks are found to respond to blue light optical stimulation as well and therefore may play a crucial role in real time OSL radiation dosimetry in the regime of low temperature ambient conditions, especially with improved detection threshold.
