thermoluminescent
Thermoluminescence is a form of luminescence in which a material emits light when heated after having been exposed to radiation. Materials that exhibit this behavior are described as thermoluminescent. In crystalline solids, exposure to ionizing radiation creates trapped charge carriers at defects in the lattice. When the material is subsequently heated, these trapped electrons gain enough energy to escape and recombine at luminescent centers, releasing photons typically in the visible or near-UV range.
The intensity of the emitted light, and the resulting glow curve as a function of temperature, depend
Applications include thermoluminescent dosimetry (TLD), where the light output is used to measure ionizing radiation doses
Some practical considerations include fading of the signal over time, the need for annealing to erase previous
