Abstract
dating 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. (C) 2010 Elsevier Ltd. All rights reserved.
