Abstract:

The results of the study both on short-wavelength luminescence and point defects in the large LiB3O5 crystals grown by the advanced technique are reported. It was revealed that corpuscular-or photon radiation with energy exceeding E(g) efficiently excites the complex broad luminescence band at 290 nn. Decay kinetics involves a principal fast component with lifetime of 4 ns and several components of millisecond range. On irradiation at 77 K, LiB3O5 crystals yield the new ESR-signals, resulted from the B(2+)election and O- hole trapped centers which are stable at temperatures below RT. The obtained data suggest that these centers are responsible for the radiation-induced optical absorption band at 306 nm. We also investigated accumulation and thermal annealing of the point defects. The most acceptable models of defects, recombination processes with defects participation and the origin of the LiB3O5 short-wavelength luminescence are discussed.
