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 (Ee = 10 MeV, D = 100–160 kGy, Φmax = 5 × 1015 electrons/cm2) 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. © 2021 Elsevier B.V.

All the crystals examined were grown in framework of the state assignment of IGM SB RAS. The X-ray excited measurements were performed at the shared research center SSTRC based on the VEPP-4—VEPP-2000 complex at Budker Institute of Nuclear Physics, Siberian Branch of the Russian Academy of Sciences (Novosibirsk, Russia) using equipment supported by project RFMEFI62119X0022 .
