Over the last 60 years, luminescence dating has developed into a robust chronometer for applications in earth sciences and archaeology.
The technique is particularly useful for dating materials ranging in age from a few decades to around 100,000–150,000 years.
Growth curves are unique to each sample being analyzed such that new measurements have to be made and a new curve constructed for every sample being dated. Examples of growth curves for quartz taken to saturation (redrawn after ).

An energy level diagram that illustrates how ionizing radiation creates luminescence centers in crystal lattices (redrawn from Ref. (a) Following irradiation, electrons are expelled from their original sites leaving holes behind.
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.
In this chapter, following a brief outline of the historical development of the dating method, basic principles behind the technique are discussed.
This is followed by a look at measurement equipment that is employed in determining age and its operation.So by measuring carbon 14 levels in an organism that died long ago, researchers can figure out when it died.The procedure of radiocarbon dating can be used for remains that are up to 50,000 years old.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.Standard bialkaline photomultipliers (PMT) and EMI 9235QB PMTs do not detect emissions beyond 650 nm, whereas electron multiplying CCD (EMCCD) cameras can capture the whole range (modified after Ref. (a) When using the additive dose method, incremental doses are administered on top of the natural dose and then measured.
