Thermoluminescence (TL) dating is a scientific technique used to determine the age of artifacts by measuring the light emitted when a material, such as pottery or minerals, is heated. Over time, these materials absorb natural radiation from their surroundings, trapping electrons in the mineral's crystal structure. When these materials are heated, the trapped electrons are released in the form of light, or luminescence, and the intensity of this light can be measured to determine how long it has been since the material was last heated or exposed to sunlight.

In archaeology, TL dating is primarily applied to ceramics, sediments, and geological deposits. Its significance lies in its ability to date objects that were heated or fired, such as pottery or bricks, up to 500,000 years ago, far beyond the range of radiocarbon dating, which only works for organic materials. The technique plays an essential role in dating ancient human habitation sites, geological layers, and artifacts.

However, TL dating requires careful handling of samples, as contamination can affect accuracy. It also depends on precise knowledge of the environmental radiation dose rate and requires the object to have been heated to a high enough temperature in the past. Despite these limitations, thermoluminescence is a critical tool in archaeology, contributing to our understanding of early civilizations and geological history. Advances in TL technology continue to improve its accuracy, broadening its application to both archaeological and planetary studies..
