Optically Stimulated Luminescence Dating Of Young Quartz Using The Fast Component, Alastair C. Cunningham, Jakob Wallinga

Faculty of Science, Medicine and Health - Papers: part A

have attempted to isolate the fast component of the quartz optically stimulated luminescence (OSL) signal using a curve-fitting procedure. By pre-determining the decay constants, the procedure is simple enough to be scripted, allowing a large number of aliquots to be processed. A Monte Carlo error routine is used, in which simulated decay curves are fitted with several exponentials, which vary in their decay rates according to the measured distributions of fast and medium component decay rates. The derived error term is closely related to the intensity of the fast component signal, but is also influenced by the degree of similarity …
