Materials on the Quaternary Period of the Ukraine. 3 History edit The concept of using luminescence dating in archaeological contexts was first suggested in 1953 by Farrington Daniels, Charles. 10 The traditional OSL method relies on optical stimulation and transfer of electrons from one trap, to holes located elsewhere in the lattice necessarily requiring two defects to be in nearby proximity, and hence it is a destructive technique.

Stimulating these mineral grains using either light (blue or green for OSL; infrared for irsl) or heat (for TL) causes a luminescence signal to be emitted as the stored unstable electron energy is released, the intensity of which varies depending on the amount of radiation. "Optically stimulated luminescence dating of sediments over the past 250,000 years". A sample in which the mineral grains have all been exposed to sufficient daylight (seconds for quartz; hundreds of seconds for potassium feldspar) can be said to be of zero age; when excited it will not emit any such photons.
