The problem of dating quartz 1: Spectroscopic ionoluminescence of dose dependence
چکیده انگلیسی

A suite of quartz samples of different provenances, irradiation, thermal and depositional histories were analysed using spectroscopic ionoluminescence (IL) to investigate variations in emission spectra as a function of cumulative radiation dosing. Protons were selected for implantation to mimic the effect of natural radiation over geological timescales. All samples exhibited depletion in the UV–violet emission (3.2–3.4 eV) with increasing cumulative dose, whilst the red emission (1.8–1.9 eV) increased. A power–law relationship exists between the two emissions. It is inferred that the luminescence emission of quartz is indicative of its radiation history, and spectral analyses could be used to determine the utility of different quartz samples for optically stimulated luminescence dating (OSL) where the detection range is limited to 3.4–4.6 eV.
