This trapped signal is light sensitive and builds up over time during a period of no light exposure during deposition or burial but when exposed to light natural sunlight or artificial light in a laboratory the signal is released from the traps in the form of light — called luminescence. In this facility we aim to sample these minerals found in all sediments without exposing them to light so that we can stimulate the trapped signal within controlled laboratory conditions with heat thermoluminescence — TL or light optically stimulated-luminescence — OSL. As most sedimentary processes or events are based on the deposition of sediment these depositional ages are critical to geomorphological research.
Luminescence dating is a geochronological technique important for reconstructing past environments on Earth over the last million years see Smedley, for details.
Main responsibilities: To design, set-up and carry out experiments to characterise the luminescence. For admission to the selection process referred to in Art. The materials will be endowed with fast dynamics and flexibility, optimal gas capacity, especially for CH4, and luminescence properties.
