thermoluminescence
The release of previously absorbed radiation upon being heated
Luminescence exhibited by a substance on being moderately heated
Emission of light from certain heated substances as a result of previous exposure to high-energy radiation. The radiation causes displacement of electrons within the crystal lattice of the substance. Upon heating, the trapped electrons return to their normal, lower-energy positions, releasing energy in the process. The longer the substance is exposed to radiation, the greater is the energy released. By measuring the amount of light given off, the duration of exposure to radiation can be determined; thus, thermoluminescence has been used to determine the age of various minerals and archaeological artifacts
It is shown esp
by certain substances that have been exposed to the action of light or to the cathode rays
