Abstract:

The results of an investigation of the thermally stimulated emission of electrons and photons in lithium triborate single crystals are presented. The investigation is performed mainly by simultaneously measuring the thermally stimulated emission of electrons and photons after various radiation treatments. In particular, the thermally stimulated exoelectron emission of LiB3O5 crystals is discovered for the first time and studied in detail. An analysis of the experimental results reveals two new trapping centers. It is established that the thermal annealing of these centers at 450 and 515 K makes a contribution only to the exoelectron emission. It is postulated that a field fluctuation process, which lowers the potential barriers of the trapping centers, takes place in LiB3O5 at 100-140 K. This process is attributed to thermally stimulated relaxation of the radiation-induced charge. A significant dependence of the parameters of the thermally stimulated processes in LiB3O5 on the parameters of the radiation treatment is discovered.
