关于TLD-100样品热释光现象的几点讨论

Discussion on Thermoluminescence of LiF∶Mg∶Ti(TLD 100)Crystals

本文对ＴＬＤ１００（ＬｉＦ∶Ｍｇ∶Ｔｉ）样品的三维热释光（ＴＬ）谱进行了测量和分析，观测到了经室温辐照的样品具有６４℃、１１６℃、１５６℃、１９０℃、２１８℃的发光峰及若干个高温峰；其发射谱主要由２．６７ｅＶ、２．８２ｅＶ、３．１９ｅＶ及３．３４ｅＶ等４个发光带组成。本文还对辐照后的样品进行了吸收光谱的测量。结合前人的报告。

The 3 demensional thermoluminescence(3D TL)spectra of TLD 100 samples have been recorded and analyzed.Thermal emissions at 64℃,116℃,156℃,190℃,218℃ and higher temperatures are detected in the samples irradiated at room temperature.The spectrum of every thermal emission consists of 4 main bands at 2.67eV,2.82eV,3.19eV and 3.34eV,respectively.TL emission mechanism is discussed based on the studies of the optical absorption spectra with the reference to the previous reports.
