摘要：

Thermoluminescence (TL) emission spectra in the visible and near infrared region of TLD-300 (CaF2:Tm) commonly used for TL dosimetry were studied at exposures 286 and 7300 R. The TL emission spectra from 300 to 900 nm are observed every 2-degrees-C from 50-degrees-C to 320-degrees-C. Glow peaks appear at 110-degrees-C, 145-degrees-C, 235-degrees-C and 265-degrees-C. Emission bands in the spectra were measured at 357, 460, 655 and 805 nm. Discussion is given about a possibility of using the infrared emission band 805 nm as well as the visible emission bands in the routine work of radiation detector dosimetry at a temperature of around 145-degrees-C. Further we discuss the change of the integral glow curve for each of these emission bands for the exposure radiation at 286 and 7300 R.
