Tenebrescence has been reported to have a high potential for personal ultraviolet (UV) detection. Color changes can detect UV doses and can also be used as visual sensors for X-rays. Hackmanite is known to exhibit tenebrescence. This study investigated the kinetics of electron-trapping levels contributing to the luminescence of NaAlSiO(Cl,S) hackmanite using thermoluminescence. The glow curves were measured at a heating rate of 5 K/s on hackmanite irradiated with X-rays. The physical parameters of the electron-trapping levels were evaluated by analyzing them using the deconvolution, peak shape, and initial rise methods. The NaAlSiO(Cl,S) hackmanite had at least five trapping levels, with activation energies of 0.78, 1.12, 1.86, 1.26, and 1.18 eV and corresponding peak trap lifetimes of 3.59, 2.71, 1.47, 3.34, and 3.91 s, respectively. The estimated migration time was 15.0 s.
据报道，紫磷锰矿具有很高的个人紫外线（UV）检测潜力。颜色变化可以检测紫外线剂量，还可以用作X射线的视觉传感器。已知紫方钠石会呈现紫磷光现象。本研究使用热释光研究了有助于NaAlSiO(Cl,S)紫方钠石发光的电子俘获能级的动力学。在以5 K/s的加热速率对用X射线辐照的紫方钠石进行测量时得到了发光曲线。通过使用去卷积、峰形和初始上升方法对电子俘获能级进行分析，评估了其物理参数。NaAlSiO(Cl,S)紫方钠石至少有五个俘获能级，其激活能分别为0.78、1.12、1.86、1.26和1.18 eV，相应的峰陷阱寿命分别为3.59、2.71、1.47、3.34和3.91 s。估计迁移时间为15.0 s。
