Abstract
An analysis of the linear modulation-OSL (LM-OSL) peak and the main TL peak from irradiated Al2O3:C is presented. Data are presented indicating that the LM-OSL peak is composed of three overlapping components originating from populated traps with optical cross sections of 10(-18) - 10(-20) cm2. Studies of the main TL peak before and after LM-OSL measurement indicate that the first two LM-OSL components, corresponding to traps with the largest optical cross sections, originate from traps which also contribute to the low temperature side of the TL peak and that the third component, corresponding to the traps with smallest optical cross section, are due to traps that contribute to the high temperature side of the TL peak. Some consequences for dosimetry are discussed.
