thermoluminescence

Thermoluminescence is a natural phenomenon where certain materials, like minerals or archaeological artifacts, emit light when they are heated. This process occurs because these materials trap energy from environmental radiation over time. When heated, the stored energy is released as visible light. Scientists use thermoluminescence to date objects, especially in archaeology, by measuring the amount of light emitted to determine how long it has been since the material was last heated. This method provides insight into historical timelines and helps in understanding past human activities and natural events.
