The luminescence emission of quartz is used in optically stimulated luminescence dating (OSL), however the precise origins of the emission are unclear. A suite of quartz samples were analysed using X-ray excited optical luminescence (XEOL). Radiation dose effects were observed whereby the UV emissions (3.8 and 3.4 eV) were depleted to the benefit of the red emission (1.9-2.0 eV). Samples were excited at similar to 7 keV. Understanding why some quartz emit light more brightly than others will increase the efficiency and precision of OSL analyses. (C) 2011 Elsevier Ltd. All rights reserved.</p
