WebThermoluminescence (TL) is luminescence that arises on gentle warming of a material and usually occurs below incandescence. Reading the sample by heating it destroys the activation, so the readout is a single-shot experiment. Most TL materials can, however, be reactivated and used repeatedly. The mechanism of TL is shown in Fig. 18.
