比较了三种类型石英的辐射发光(RL)谱和波长分辨热刺激发光(TSL)测量的结果。一种详细的高斯分量的数值反卷积，允许识别哪一种类型的发光过程涉及到哪些波段。在长时间照射的样品中，在2.51 eV处的蓝色“A带”被证实是RL和TSL光谱的主要成分。110℃TSL峰的紫外光发射是复合的。与以前报道的RL光谱类似，在500℃下退火10分钟，在3.42 eV处引起了“C带”的强烈增强。这一效应在天然和预辐照的石英中尤为明显。第二个强烈的紫外光成分，即3.7 eV的“M带”，被发现对在1000℃下10℃退火的样品的TSL和RL光谱都有贡献。更广泛的紫外光发射似乎只涉及RL发射，而不涉及TSL发射。
The radioluminescence (RL) spectra of three types of quartz have been compared to those obtained from wavelength resolved thermally stimulated luminescence (TSL) measurements. A detailed numerical deconvolution into Gaussian components allowed to identify which of the bands are involved in either types of luminescence processes. The blue “A band” at 2.51 eV was confirmed to dominate both RL and TSL spectra in samples exposed to prolonged irradiation. The UV emission of the 110 °C TSL peak was found to be composite. Analogously to what previously reported for RL spectra, an annealing at 500 °C for 10 min induced a strong enhancement of the “C band” at 3.42 eV. This effect was particularly evident in natural and pre-irradiated quartz. A second intense UV component, the “M band” at 3.7 eV, was found to contribute to both TSL and RL spectra of samples annealed at 1000 °C for 10 min. A further broad UV emission seems to be involved only in RL emission but not in the TSL one.
