Glass displays from mobile phones show a characteristic thermoluminescence (TL) signal after the exposure to ionizing radiation. Therefore they can be used as accident and emergency dosimeters. This paper carries out quantitative analysis of such TL signals by using several standard methods of analyzing luminescence signals. Application of the initial rise method to 120 TL glow curves obtained by the Tmax-Tstop method, shows that the TL signals can be described by a quasi-continuous distribution of energies in the range of E=0.8-1.5 eV. The shape of the TL signals was simulated by using five Gaussian trap energy distributions centered at five discrete activation energy values and a single frequency factor s. The result of the simulations were in a good quantitative agreement with all the experimental TL glow curves. Two additional experiments investigating the variation of the TL signal with the heating rate, and studying the fading of the TL signal at room temperature over long periods of time, showed that this material exhibits the well known anomalous heating rate effect, and anomalous fading of the TL signal. The results of these two experiments demonstrate that the luminescence mechanism in this dosimetric material is rather complex, and that additional recombination pathways affect the luminescence process during a TL measurement.

手机的玻璃显示屏在暴露于电离辐射后会显示出特征性的热释光 (TL) 信号。因此，它们可用作事故和应急剂量计。本文通过使用几种分析发光信号的标准方法对此类 TL 信号进行了定量分析。将初始上升方法应用于通过 Tmax-Tstop 方法获得的 120 TL 辉光曲线，表明 TL 信号可以通过 E=0.8-1.5 eV 范围内的准连续能量分布来描述。通过使用以五个离散激活能量值和单个频率因子 s 为中心的五个高斯陷阱能量分布来模拟 TL 信号的形状。模拟结果与所有实验 TL 辉光曲线具有良好的定量一致性。两个额外的实验研究了 TL 信号随加热速率的变化，并研究了 TL 信号在室温下长时间的衰减，表明该材料表现出众所周知的异常加热速率效应，以及 TL 信号的异常衰减。 TL 信号。这两个实验的结果表明，这种剂量学材料的发光机制相当复杂，并且额外的重组途径会影响 TL 测量过程中的发光过程。
