Abstract
The study of thermoluminescence and photoluminescence spectra allows us to propose a thermoluminescence mechanism for MgB4O7:Dy,Na, which is similar to that previously known for MgB4O7:Tm. Here, the release of holes from the hole trapping center gives rise to the main working peak of thermoluminescence. The fading of dose information in MgB4O7:Dy,Na thermoluminescent detectors (TLD-580N) exposed to light (365, 395, and 470 nm) is also studied. The thermoluminescence peaks diminish without any pronounced optically stimulated luminescence. According to the proposed model, light releases electrons, which recombine with holes in hole traps, after which thermoluminescence becomes impossible.
