Abstract
The thermoluminescence of ultraviolet-(250 nm) and X-ray-irradiated KCl: Eu 2+ is investigated. The peaks are located in the same positions independent of the radiation used to excite the sample, with differences only in the peak intensity ratios. Thermal and optical bleaching methods allow us to relate the thermoluminescence peaks located in the low-temperature region (320-425 K) to F z centres and those in a higher-temperature region (425-530 K) to F centres.
