Mature roulette chat - Future directions of luminescence dating of quartz

Makaiko Chithambo also has a long-standing interest in the use of conventional thermoluminescence and thermoluminescence spectra to understand physical processes of luminescence in materials and has studied a wide range of natural and synthetic materials including beryl, carbonatite, polyethylene, quartz, Sr Al2O4: Eu2 , Dy3 , α-Al2O3: C and α-Al2O3: C, Mg.On the over-arching theme of point-defects in solids, he also collaborates with others to exploit the utility of allied methods such as positron annihilation and the like.Reza Sohbati is a postdoctoral researcher at the Nordic Laboratory for Luminescence Dating, Aarhus University, Risø, Denmark.

Optical dating using the optically stimulated luminescence (OSL) signal of quartz and the infra-red stimulated luminescence (IRSL) signal of feldspar was developed later; these techniques were specifically focused at isolating only the most light sensitive components of the trapped charge populations.

The single aliquot regenerative-dose (SAR) OSL protocol for quartz developed around 15 years ago revolutionized luminescence dating, providing a widely applicable and reliable method to date sediments.

His interest in luminescence goes back a long way, 1984 to be exact, when he started TL dating of loess in China.

Sheng-Hua has studied and worked in Laboratories of Zhengding, Oxford, Aberystwyth and The University of Hong Kong.

His main research interest is the study of mechanisms of luminescence in materials using time-resolved optical stimulation for which he has developed instrumentation, theory and analytical methods.

Dr Chithambo has used the technique to study quartz, feldspar and α-Al2O3: C addressing a wide range of questions including the influence of annealing, thermal history, and the link between sensitivity and luminescence lifetimes in quartz and also developing analytical methods for studying the influence of measurement temperature on lifetimes and luminescence throughput in α-Al2O3: C.In luminescence she has been involved in the development of the pulsed OSL/IRSL and post-IR IRSL dating methods and specialises in the area of dating volcanic rocks.In ESR she developed the ESR SAR protocol for quartz.He has the distinction of having attended all LED conferences since the 1987 one held in Cambridge. Sumiko Tsukamoto works at the Geochronology and Isotope Hydrology Section at Leibniz Institute of Applied Geophysics, Hannover, Germany and manages the Luminescence and ESR laboratories.Since the completion of her Ph D in ESR she has become one of the very few specialists who actively conduct both luminescence and ESR research and publish widely in both fields.The limits of robust interpretation of luminescence age estimates, and the problems that approaches currently under development may help address, will be examined, including applications to other planets.
