A simple method to record thermoluminescence glow-curves between 77 and 300 K

In this work a simple method is suggested for recording thermoluminescence in the temperature region between 77 K (Liquid nitrogen temperature) and 300 K (environmental temperature). The method is based on an exponential heating scheme instead of linear heating of the sample. The experimental setup required is much simpler than that of conventional thermoluminescence readers. In the present work it was possible to measure thermoluminescence glow-curves of materials which are widely used in dosimetry, using a very simple setup. Specifically, we measured the thermoluminescence glow-curves of LiF:Mg,Ti, Al2O3:C and of different quartz samples, unfired and fired at very high temperatures. Furthermore, a glow-curve de-convolution analysis of the TL glow-curves of LiF:Mg,Ti and Al2O3:C is performed using newly developed analytical expressions describing a single TL peak obtained under an exponential heating scheme.
