Scientists in North America first developed thermoluminescence dating of rock minerals in the 1950s and 1960s, and the University of Oxford, England first developed the thermoluminescence dating of fired ceramics in the 1960s and 1970s.During the 1970s and 1980s scientists at Simon Frasier University, Canada, developed standard thermoluminescence dating procedures used to date sediments.Thermoluminescence dating of this profile gives new information about the influence of local conditions on the results of TL analysis.As much as 75% of the obtained results are distinctly overestimated, even by several hundred per cent, that is untypical of regional loess profiles.In 1985, they also developed optically stimulated luminescence dating techniques, which use laser light, to date sediments.

A review of the application of thermoluminescence (TL) methods for dating sediments is presented.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.Over time energy (in the form of more and more trapped electrons) is stored in these structural imperfections.By heating the ceramic or mineral to above 500 degrees Celcius, these trapped electrons are released, creating a flash of light called thermoluminescence.
