The luminescence properties of BaMgF4 ceramics synthesized using electron beam-assisted synthesis were investigated under vacuum ultraviolet (VUV) synchrotron excitation at a cryogenic temperature T = 9 K. Their spectra, measured over the 4–10.8 eV range, and corresponding spectra revealed complex multicomponent structure with emission maxima 3.71, 3.55, 3.33, 3, ~2.8 eV. primary band 330 nm was attributed to self-trapped excitons (STE) excited near edge (9.3–9.7 eV), indicating interband transitions subsequent excitonic relaxation. Bands 3 associated defect states efficiently 6.45 eV, 8 high-energy 10.3 spectrum showed distinct 5, 6.45, which interpreted as excitations defect-related states. These results highlight interplay between transitions, processes, luminescence, defines dynamics ceramics. findings confirm that radiation introduces centers influencing luminescent properties, making promising material for VUV UV applications.
