本文研究了石英晶体在190 K附近的热释光（TSL）峰，该峰仅在双辐照后出现，并与在相同双辐照过程下出现的电子自旋共振（ESR）谱平行。研究表明，由于[SiO 4/Li] 0中心的缺陷，190 K峰和新的四线ESR谱之间存在完全相关性。两者都是在完全相同的条件下形成的，当石英晶体在室温附近受到大剂量的辐射后，两者都不存在，并且两者都被晶体的氢吹扫（即电扩散）消除。除了相关性，190-K TSL峰值的具体特征进行了描述。这些包括辐射导致190-K峰的动力学从第一级变为接近第二级的效应。同时峰值温度下降约6 K。这些结果的解释是遵循从TSL的动力学理论。
The thermally stimulated luminescence (TSL) peak in quartz near 190 K, which appears only after undergoing double-irradiation, has been studied in parallel with an electron-spin-resonance (ESR) spectrum appearing under the same double-irradiation procedure. This study revealed a full correlation between the 190-K peak and the new four-line ESR spectrum due to the defect we have labeled the [SiO 4/Li] 0 center. Both were formed under exactly the same conditions, both were absent after subjecting the quartz crystal to heavy doses of radiation near room temperature, and both were eliminated by hydrogen sweeping (ie, electrodiffusion) of the crystal. In addition to the correlation, specific characteristics of the 190-K TSL peak are described. These include an effect in which radiation caused the kinetics of the 190-K peak to change from first to nearly second order. At the same time the peak temperature dropped by about 6 K. The explanation of these results is shown to follow from the kinetic theory of TSL.
