This study delves into the synthesis and characterization of luminescent ceramics based on tungstenactivated magnesium fluoride (MgF2) complemented with varying concentrations of lithium hydroxide (LiOH). Utilizing a distinctive sintering process conducted in an open-air milieu under robust radiation conditions, we successfully synthesized a series of tungsten-activated ceramics. Study revealed that the resultant ceramics prominently display luminescent properties, which can be excited by UV radiation in the spectrum of 200-300 nm, as well as by high-energy electron fluxes. The spectral characteristics of these ceramics, in terms of band position, half-width, and excitation spectra, are strikingly analogous to those observed in LiF crystals activated by tungsten and titanium ions. This observation led to the conclusion that luminescent centers, similar to those in LiF crystals, are formed during the ceramic synthesis.
