http://www.brussels-art-labo.com/en/thermoluminescence-dating/ WebThe thermoluminescence dating. consists in measuring the intensity of the light emission which emanates from a tiny sample taken from a ceramic object after having warmed it to a temperature of about 500° C. Knowing that the luminescence is proportional to the time elapsed since the manufacture of the ceramic, the age of the latter can be obtained by …
http://www.brussels-art-labo.com/en/thermoluminescence-dating/ Lorsqu’il est question de datation d’un matériel archéologique, on s’intéresse à l'accumulation d'énergie dans les différents matériaux composant l'objet étudié depuis son existence. Cette énergie provient de la radioactivité de l'environnement ambiant. Un cristal comme le quartz, qui est présent dans plusieurs minéraux, est capable d'accumuler cette énergie avec ses failles cristallines . Cette énergie consiste en l’accumulation d’électrons qui se retrouvent dans un état …
Thermoluminescence emits a weak light signal that is proportional to the radiation dose absorbed by the material. It is a type of luminescence dating . The technique has wide application, and is relatively cheap at some US$300–700 per object; ideally a number of samples are tested. See more Thermoluminescence dating (TL) is the determination, by means of measuring the accumulated radiation dose, of the time elapsed since material containing crystalline minerals was either heated (lava, ceramics) … See more Another important technique in testing samples from a historic or archaeological site is a process known as thermoluminescence … See more Optically stimulated luminescence dating is a related measurement method which replaces heating with exposure to intense light. The sample material is illuminated with a very bright source of green or blue light (for quartz) or infrared light (for potassium feldspar See more 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.

WebJan 1, 1985 · 1. Basis of thermoluminescence dating. The initial geological TL level is reduced to (a) zero in the case of heated archaeological materials or authigenic growth of crystals, or (b) a small residual level to in the case of sediments, primarily as a result of sun exposure during predepositional transport.
