Question: How is thermoluminescence used as a dating method?

Thermoluminescence can be used to date materials containing crystalline minerals to a specific heating event. When a specimen is reheated, the trapped energy is released in the form of light (thermoluminescence) as the electrons escape. The amount of light produced is a specific and measurable phenomenon.

What does thermoluminescence dating TL dating involve?

Thermoluminescence dating (TL) is the determination, by means of measuring the accumulated radiation dose, of the time elapsed since material containing crystalline minerals was either heated (lava, ceramics) or exposed to sunlight (sediments). Sediments are more expensive to date.

Which method of dating uses light?

Luminescence dating Luminescence dating refers to a group of methods of determining how long ago mineral grains were last exposed to sunlight or sufficient heating. It is useful to geologists and archaeologists who want to know when such an event occurred.

What are thermoluminescent materials?

In general, thermoluminescence is a form of luminescence. It is exhibited by certain crystalline materials, such as calcium fluoride, lithium fluoride, calcium sulfate, lithium borate, calcium borate, potassium bromide, and feldspar.
