A Study on the Correction of the Trap Depth Value for Low Temperature TL Peak of Quartz

One of the significant factors that should be examined when performing a thermoluminescence (TL) study related to a natural material is the detection of the trap depth. The various heating rate (VHR) method is one of the practical methods used in the calculation of the trap depth. Even though the HRs used in TL measurements do not affect the trap depth of the thermoluminescent materials, the corrected TL peak data should be used in the calculation of the trap depth. In this paper, low temperature TL glow peak of natural quartz (NQ) was recorded by using different linear HRs between 0.5 and 10 K/s from room temperature (RT) to 425 K by applying the same irradiation with the beta dose of 0.5 Gy. The trap depth of NQ sample was calculated using VHR method for both experimental and corrected TL glow peaks of NQ. The trap depth values were found to be 0.57 ± 0.03 and 0.79 ± 0.04  eV with VHR and Mott-Seitz correction methods, respectively.
