Thermoluminescence dating is the determination, by means of measuring the accumulated radiation dose, of the time elapsed since material containing crystalline minerals was either heated or exposed to sunlight. As the material is heated, during measurements, thermoluminescence, a weak light signal, is emitted, proportional to the radiation dose absorbed by the material. Natural crystalline materials contain imperfections: impurity ions, stress dislocations, and other phenomena that disturb the regularity of the electric field that holds the atoms in the crystalline lattice together. This leads to local humps and dips in its electric potential. Where there is a dip, a free electron may be attracted and trapped. The flux of ionizing radiation—both from cosmic radiation and from natural radioactivity—excites electrons from atoms in the crystal lattice into the conduction band where they can move freely. Most excited electrons will soon recombine with lattice ions, but some will be trapped, storing part of the energy of the radiation in the form of trapped electric charge.

Thermoluminescence dating

Thermoluminescence can be broken into two words: Thermo , meaning head and Luminescence , meaning an emission of light. It essentially means that some materials that have accumulated energy over a long period of time will give off some light when exposed to high heat. Ceramics are made from geological material, inorganic material, right?

They use clay and sand and a bunch of other stuff from the ground to make these pieces. And all these geological things contain radiation.

Collective term for techniques that assign specific dates or date ranges, dating and thermoluminescence), data correlation (as in dendrochronology), and a.

The definition of thermoluminescence in the dictionary is phosphorescence of certain materials or objects as a result of heating. It is caused by pre-irradiation of the material inducing defects which are removed by the heat, the energy released appearing as light: used in archaeological dating.

Luminescence Dating

Most of the chronometric dating methods in use today are radiometric. That is to say, they are based on knowledge of the rate at which certain radioactive isotopes within dating samples decay or the rate of other cumulative changes in atoms resulting from radioactivity. Isotopes are specific forms of elements.

Thermoluminescence is defined as the burst of light emission at various temperatures (TL) and optically stimulated luminescence (OSL), or optical dating.

Thermoluminescence , emission of light from some minerals and certain other crystalline materials. The light energy released is derived from electron displacements within the crystal lattice of such a substance caused by previous exposure to high-energy radiation. The intensity of the emission can be correlated to the length of time that a given substance was exposed to radiation; the longer the time allowed for the radiation to build up an inventory of trapped electrons, the greater the energy released.

Because of this feature, thermoluminescence has been exploited as a means of dating various minerals and archaeological artifacts. Article Media. Info Print Cite. Submit Feedback.

Thermoluminescence dating is the determination of the date at which materials were formed by measuring the light energy released when heating it. The natural flux of ionizing radiation – both from cosmic radiation as well as natural radioactivity – can put crystalline structures in excited states storing some of the energy of the radiation. A very small fraction can stay in these excited states for long time.

When such material is heated the stored energy is released as weak light, the so called thermoluminescence. After cooling and re-heating it will not show the light anymore, as no excited states remain. Thermoluminescence dating is used for material where radiocarbon dating is not available, like sediments.
