Electrons from these substances get trapped in the mineral's crystalline structure, and continuing exposure of the rocks to these elements over time leads to predictable increases in the number of electrons caught in the matrices.

Luminescence dating refers to a group of methods of determining how long ago mineral grains were last exposed to sunlight or sufficient heating.Luminescence dating is good for between a few hundred to (at least) several hundred thousand years, making it much more useful than carbon dating.The term luminescence refers to the energy emitted as light from minerals such as quartz and feldspar after they've been exposed to an ionizing radiation of some sort.The equations used by scholars to determine the date when the last exposure happened are typically: Where De is the laboratory beta dose that induces the same luminescence intensity in the sample emitted by the natural sample, and DT is the annual dose rate comprised of several components of radiation that arise in the decay of natural radioactive elements.See Liritzis et al.'s excellent 2013 book on Luminescence Dating for more information on these processes.
