英文摘要: Abstract(#br)The purpose of the present work is to examine the effect of heating (up to 500°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 ∘ C , the shape of a growth curve will change, and the saturation level of a...
