模拟(自然)石英发光(TL/OSL)现象如今似乎相当普遍。相应的模拟能够为电荷传输系统提供有价值的见解。相比之下，模拟石英的辐射荧光(RF)在过去被忽略了。本文介绍并讨论了(1)在UV波段测量的天然石英的射频信号和(2)用三能级模型对这些实验进行的模拟，以解释实验结果。两个天然石英样品在室温(RT)下经过不同的预热程序进行了研究：(A)连续将预热温度从50°C提高到700°C；(B)重复500°C的预热，然后在RT下进行11次UV-RF测量。在测量和模拟结果的基础上，我们最终从理论上证实了石英的UV-RF信号与埋藏剂量的相关性。
Modelling (natural) quartz luminescence (TL/OSL) phenomena appears to be quite common nowadays. The corresponding simulations are capable of giving valuable insights into the charge transport system. By contrast, simulating radiofluorescence (RF) of quartz has rather been neglected in the past. Here we present and discuss (1) the RF signals of natural quartz measured in the UV band and (2) simulations of these experiments executed using a three-energy-level model to explain the experimentally obtained results.Two natural quartz samples were investigated at room temperature (RT) following different preheat procedures: (a) consecutively increasing preheat temperatures from 50 °C to 700 °C and (b) repeating a 500 °C preheat with subsequent UV-RF measurement at RT for eleven times. Based on the measurement and modelling results, we finally confirm theoretically the dependency of the UV-RF signal of quartz on the burial dose.
