In 2004-2005 the facilities underwent major refurbishment with the building and equipping of new expanded laboratory space.

Both quartz and many feldspar minerals act as dosimeters recording their exposure to this ionizing radiation. With careful measurements luminescence can be used to establish the total amount of accumulated dose since the last resetting event.

After being exposed to radiation these minerals, when stimulated by either heat or light, emit light. The amount of luminescence emitted is proportional to accumulated dose since the minerals were last exposed to heat, e.g. This when combined with measurement of the present-day annual ionizing dose rate can be used to calculate an age.

Located in the basement of Bessey Hall on UNL's City Campus, the Luminescence Geochronology Laboratory specializes in optically-stimulated luminescence (OSL) dating of Quaternary fluvial, eolian, and coastal deposits.

This "dark (amber-light only) lab" contains rooms for sample storage, sample preparation, and OSL readers. This lab primarily serves UNL faculty and graduate students, but collaborative research is ongoing with colleagues from other institutions.

The University of Georgia Luminescence Dating Laboratory began operations in early 2002.
