SelectedFrequency Thermoluminescence Characteristic of Jixi’s Fluorite in Anhui Province

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.
