How does thermoluminescence dating work
WebThermoluminescence dating is used mostly on pottery and other inorganic materials such as burnt flint. It’s a very popular dating method in archaeology because not only can it … WebThere are two variants of luminescence dating: thermoluminescence (TL) and optically stimulated luminescence (OSL), or optical dating. The dating information is carried in the form of trapped electrons; these are electrons which have been ionized by nuclear radiation and which have diffused into the vicinity of a defect in the lattice that is ...
