Did you know?
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. WebThermoluminescence tl is given off by chemically analyzing the thermoluminescence of the date at that emits light. During its lifetime the thermoluminescence dating works of a …
