Thermoluminescence dating dictionary
Luminescence dating including thermoluminescence and optically stimulated luminescence is a type of dating methodology that measures the amount of light emitted from energy stored in certain rock types and derived soils to obtain an absolute date for a specific event that occurred in the past. The method is a direct dating technique , meaning that the amount of energy emitted is a direct result of the event being measured.
Better still, unlike radiocarbon dating , the effect luminescence dating measures increases with time. As a result, there is no upper date limit set by the sensitivity of the method itself, although other factors may limit the method’s feasibility.

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.

View exact match. Display More Results. It is based on the principle that ceramic material, like other crystalline non-conducting solids, contains small amounts of radioactive impurities such as potassium, uranium, and thorium, which emit alpha and beta particles and gamma rays causing ionizing radiation. This produces electrons and other charge-carriers holes which become caught in traps in the crystal lattice.
Heating of the pottery causes the electrons and holes to be released from the traps, and they recombine in the form of thermoluminescence. The amount of thermoluminescence from a heated sample is used to determine the number of trapped electrons resulting from the absorption of alpha radiation. The quantity of light emitted will depend on three factors – the number of flaws in the crystal, the strength of the radioactivity to which it has been exposed, and the duration of exposure.
An age determination technique in which the amount of light energy released in a pottery sample during heating gives a measure of the time elapsed since the material was last heated to a critical temperature. The older a piece of pottery, the more light produced.

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.

Radiocarbon dating history definition
When a radiation is incident on a material, some of its energy may be absorbed and re-emitted as light of longer wavelength. The wavelength of the emitted light is characteristic of the luminescent substance and not of the incident radiation. Thermoluminescence TL is the process in which a mineral emits light while it is being heated: it is a stimulated emission process occurring when the thermally excited emission of light follows the previous absorption of energy from radiation.
Energy absorbed from ionising radiation alpha, beta, gamma, cosmic rays frees electrons to move through the crystal lattice and some are trapped at imperfections in the lattice. Subsequent heating of the crystal can release some of these trapped electrons with an associated emission of light.
The dating definition, thermoluminescence dating from room. Through relative dating methods of rock minerals, optical stimulated luminescence dating methods.
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.

What is thermoluminescence?
Thermoluminescence TL dating is the determination by means of measuring accumulated radiation dose of the time elapsed since crystalline mineral materials were either heated lava , ceramics or exposed to sunlight sediments.
