FIELD: chemistry.
SUBSTANCE: method of producing scintillation ceramic involves monoaxial hot-pressing high-purity BaF2-ScF3 in form of a monolithic ingot, which is a hardened melt or monocrystal or powdered mixture with dopant concentration from 0.05 to 5.0 mol % at temperature 1000-1250°C and pressure 100-200 MPa until formation of a ceramic, and then annealing the obtained ceramic in an atmosphere of gaseous CF4. The novel ceramic is used to produce a scintillator, having a working body in form of a disc, one of the bases of which serves for receiving ionising radiation, and the other for connection with a photodetector, in which the working body is made from a transparent BaF2-ScF3 ceramic with dopant concentration of 0.05-5.0 mol %.
EFFECT: production of scintillator having ultrashort luminescence lifetime and high light output.
