(Go in About Luminescence Dating) Luminescence is the emission of light from crystalline materials following the absorption of energy from an external source.

Because traps have different energy depths, some traps are not very stable at ambient temperatures and lose their electrons over the time period relevant to archaeology.

Other traps are sufficiently deep that they are not easily emptied during the exposure to heat or light.

Subsequent to zeroing, traps become refilled because of continued ionization by radioactivity and a latent luminescence signal steadily accumulates.
