FIELD: chemistry.
SUBSTANCE: group of inventions relates to the field of scintillation technology used to register ionizing radiation. Disclosed is the composition of scintillation ceramics based on yttrium alumina garnet doped with cerium ions (Ce3+:Y3Al5O12) made of a mixture of nanopowders of yttrium oxide doped with cerium ions (Ce:Y2O3), aluminum oxide (Al2O3), and yttrium oxide (Y2O3). Yttrium oxide is added to maintain stoichiometry, if necessary. The composition contains a sintering additive. Zirconium (Zr) is used as a sintering additive in the form of zirconium oxide ZrO2 with the content of 0.05-0.15 wt.%.
EFFECT: increased speed of the ceramic scintillator without reducing the glow intensity.
