| Реферат: | eng: Large single crystals of SrMgF4 (SMF), grown by the Bridgman method, were studied (T = 7-350 K, E = 1.2-6.2 eV) for both the pristine unirradiated and irradiated by an electron-beam (E-e = 10 MeV, D = 100-160 kGy, Phi(max) = 5 x 10(15) electrons/cm(2)) SMF-crystals. The optical absorption spectra at different radiation doses were determined. The luminescence spectra were studied upon excitation with visible/ultraviolet light (PL), or X-ray radiation (XRL). The PL excitation (PLE) spectra under UV-radiation, the temperature dependence curves for the luminescence intensity of steady-state XRL and PL recorded monitoring emission at different energies, as well as low-temperature thermoluminescence were studied. The paper discusses the effect of electron-beam irradiation on the optical and luminescence properties of SMF crystals, the temperature dependence of the luminescence intensity and low-temperature thermoluminescence of irradiated SMF crystals.
