Luminescent Light

USU is using the power of light to help determine the Earth’s history. Using optically stimulated luminescence geochronology, USU scientists are able to accurately determine the age of sediment samples. The luminescence reader uses controlled doses of radiation and light to incite and measure the responding light of sand grains and thus their determine age.
