What is luminescence dating
(b) At appropriate sites, electrons are trapped while holes may become localized.(c) Thermal (TL) or optical (OSL) stimulation of the material results in electrons being evicted from the traps.Continuing refinements in both methodology and equipment promise to yield luminescence chronologies with improved accuracy and extended dating range in the future and these are briefly discussed.Luminescence dating refers to age-dating methods that employ the phenomenon of luminescence to determine the amount of time that has elapsed since the occurrence of a given event.
(b) Since curve (a) appeared to underestimate some older ages, the saturating function from (a) is combined with a linear function in (b) .
In this chapter, the application of luminescence techniques in dating geological and archaeological events is examined.
Generally, the term luminescence dating is a collective reference to numerical age-dating methods that include thermoluminescence (TL) and optically stimulated luminescence (OSL) dating techniques.
Luminescence properties of minerals used in dating are then examined after which procedures used in age calculation are looked at.
Sample collection methods are also reviewed, as well as types of materials that can be dated.
