摘要: 利用BG-2003选频释光仪研究绩溪萤石的选频热释光特征。研究结果表明:绩溪萤石的热释光光子波长为280、300、310、320和460 nm,每个发光波段上都存在90、205、330和450 ℃的热释光峰。这一实验结果证明,萤石不宜用来测年,利用热释光技术测年时应尽量将其除去。Abstract: The BG-2003 selected-frequency spectrograph was used to research the selected-frequency thermoluminescence(TL) characteristic of Jixi’s fluorite. It is proved that the wavelengths of Jixi’s fluorite TL photon are 280, 300, 310, 320 and 460 nm, respectively. There are four TL peaks (90, 205, 330 and 450 ℃) in any wavelength of the five. But the experiment proves that fluorite is not an appropriate dating mineral. It should be removed when the sample is dating.
