摘要
采用质量比为1∶2、1∶1、4∶1、9∶1的4种CaSO4和SiO2混合物样品,研究CaSO4和SiO2混合物的热释光图谱。从获得的图谱中得到4个较为一致的峰,110、160、240、380℃峰。这4个峰对热释光响应均成线性且稳定。尤其是240℃峰,可用于测年研究。同时,就峰和峰的影响、峰的灵敏度变化进行了讨论。天然石膏的热释光特征可与硬石膏的相对比,为石膏样品的年龄测定提供了实验依据。
The study on the characteristics of thermoluminescence（TL） spectra for the mixture of CaSO4 and SiO2 was carried out. Four kinds of mixture of CaSO4 and SiO2 with various mass ratios, such as 1：2,1：1,4：1,9：1, were prepared and tested. Four TL peaks are 110, 160, 240, 380 ℃, and they show linearity and stabilization. Especially, the peak of 240 ℃ can be used to dating. TL characteristics of gypsum and calcium sulfate were compared. The data can help us in analysis the glow curve for gypsum. It could be useful to luminescence dating for gypsum.
