Photoluminescence dating


Luminescence dating is good for between a few hundred to (at least) several hundred thousand years, making it much more useful than carbon dating.Two forms of luminescence dating are used by archaeologists to date events in the past: thermoluminescence (TL) or thermally stimulated luminescence (TSL), which measures energy emitted after an object has been exposed to temperatures between 400 and 500°C; and optically stimulated luminescence (OSL), which measures energy emitted after an object has been exposed to daylight.

    Roberts 2006. Luminescence dating was first proposed. 50 years ago and the history of its development has been reviewed recently Wintle 2008. Prior to 1980, thermoluminescence TL had been used as a method for dating heated materials, such as pottery, and it was already known that quartz and feldspar grains were.…
