Abstract:

Thermally stimulated migration of charge carriers from trapping centers responsible for the main thermoluminescence peak at 450 K to a deep trap was experimentally observed in anion-defect alpha-Al2O3 crystals. Optically induced transport of carriers from the deep trap to the main trap was also observed to cause phototransferred thermoluminescence at 450 K. The results obtained experimentally confirm the adequacy of the basic assumptions made in the model of interactive interaction between main and deep traps in the crystals under study, as well as substantiate the method of repeated obtaining of dosimetric data.
