Response of pre-dosed TL and OSL emissions of quartz to various stimuli

Studies involving the pre-dosed OSL emission suggested it to be, broadly, similar to its TL counterpart, the 110 degrees C pre-dosed TL emission [1-3]. However, in order to have a better understanding of the relationship between the two emissions their comparative analysis based on their response to various stimuli, incorporated in these reported studies, was undertaken. Though the two signals demonstrated a definite co-relation yet some degree of disparity in their relative sensitization was observed, which seems to occur due to competition prevailing during recombination at L-centre and traps creation/destruction at high annealing temperatures of >700 degrees C. Also, the conventional and pre-dosed OSL emissions were seen to be similar in composition. (C) 2012 Elsevier B.V. All rights reserved.
