摘要	The purpose of the present work is to examine the effect of heating (up to 500 degrees C) on the shape of a growth curve for optically stimulated luminescence (OSL) of quartz extracted from Chinese loess. For OSL of natural quartz grains, the growth curve constructed using a single aliquot regenerative-dose (SAR) protocol has a linear growth part in the high dose range of > 200 Gy, which may allow the determination of a D-e to > 400 Gy and also implies that the OSL has contribution from more than a single trap/luminescence combination centre. When quartz grains are heated to a temperature of > 360 degrees C, the shape of a growth curve will change, and the saturation level of a growth curve is decreasing systematically. The significant difference in the growth curve shape before and after heating to > 370 degrees C might be used as an indicator to detect the thermal history, i.e. whether the quartz grains had undergone a heating event of > 370 degrees C before deposition. This has potential application for archaeological samples. The effect of heating on OSL sensitivity is also examined. (C) 2008 Elsevier Ltd. All rights reserved.
