The technique is particularly useful for dating materials ranging in age from a few decades to around 100,000–150,000 years.In this chapter, following a brief outline of the historical development of the dating method, basic principles behind the technique are discussed.Because this accumulation of trapped electrons begins with the formation of the crystal structure, thermoluminescence can date crystalline materials to their date of formation; for ceramics, this is the moment they are fired.The major source of error in establishing dates from thermoluminescence is a consequence of inaccurate measurements of the radiation acting on a specimen.These crystalline solids are constantly subjected to ionizing radiation from their environment, which causes some energized electrons to become trapped in defects in the molecular crystal structure.An input of energy, such as heat, is required to free these trapped electrons.Sources: “Dating In Exposed and Surface Contexts”, ed.: Beck, Charlotte.

Over the last 60 years, luminescence dating has developed into a robust chronometer for applications in earth sciences and archaeology.When scientists pull pottery from the ground, they use heat or lasers to de-excite these electrons out of their trap states back to their original state. Scientists measure the amount of light to get the total measured radiation dose (TMRD).
