摘要：

The optical absorption (OA) dose response of irradiated LiF:Mg,Ti has been measured over the dose range from 100 Gy to 1.4 M Gy. Measurements at high dose indicate that the 4.0 eV band is actually a composite band at 3.84 eV and 4.3 eV. Bleaching experiments at 5.08 eV (F band) support the participation of V-3 centers in the relaxation mechanisms following the bleach. The results are interpreted in the framework of a spatially correlated trapping center/luminescent center giving rise to composite peak 5 in the glow curve. (C) 2016 Elsevier Ltd.
