Dependence of the high temperature thermoluminescence (HTTL) in quartz on the irradiation temperature

Abstract

The dependence of the thermoluminescence (TL) intensity on the irradiation temperature (T _irr) was examined separately for the various TL peaks in the temperature range 450–700 K. One TL peak at 520 K was found to depend only slightly on T _irr. A TL peak at 460 K energed above RT rising fast with T _irr in the temperature range 200–300 K and dropping in intensity above 300 K. This TL peak was found to rise quardratically with the dose. The TL Peaks above 600 K showed a considerable rise with T _irr. These peaks rose only slightly supralinearly at low doses and with the square of the dose at high doses. A model is proposed to explain the above effects.
