Emission of light from a steadily heated material that has previously been exited by exposure to radiation. It is a form of luminescence and arises from electron displacements within the material's crystal lattice. A long time delay may elapse between excitation and subsequent light emission; this is utilized in thermoluminescent dating in archaeology.
