In this study, the role of sodium ions (Na+) in the generation of thermoluminescence (TL) peaks in the 77–680 K region of natural quartz are investigated by combining the TL and phototransferred thermoluminescence (PTTL) spectrally-resolved glow curves. The TL spectrum is characterized by four emission bands at 380, 470, 590, and 620 nm, which are related to four TL peaks at 383, 513, 598, and 648 K, respectively. The dynamic parameters of the TL peaks are evaluated using the initial rise method. PTTL is also studied in the temperature range of 77–330 K. In this region, PTTL curves show four main peaks at 160, 190, 250, and 295 K, in which the intensity of the PTTL peak at 250 K is shown to be relative to the Na+ concentration and the double irradiation process. PTTL measurements were further used to estimate the relationship between the TL peak at 598 K and PTTL peak at 383 K.

钠离子在实验室辐照天然石英的热致发光峰中的作用

在这项研究中,通过结合TL和光传递热致发光(PTTL)光谱分辨的辉光曲线,研究了钠离子(Na +)在天然石英77–680 K区域中产生热致发光(TL)峰的作用。TL光谱的特征是在380、470、590和620 nm处有四个发射带,它们分别与383、513、598和648 K处的四个TL峰有关。使用初始上升方法评估TL峰的动态参数。还研究了PTTL在77–330 K的温度范围内。在该区域,PTTL曲线显示了160、190、250和295 K处的四个主要峰,其中250 K处的PTTL峰强度显示为相对于Na +浓度和双重照射过程。进一步使用PTTL测量来估计598 K的TL峰和383 K的PTTL峰之间的关系。
