Popis:	Room-temperature scintillation properties were determined for five Eu2+ doped compounds in the Ba-Si-O ternary system: Ba2SiO4, BaSiO3, Ba2Si3O5, Ba5Si8O21, and BaSi2O5. These materials were synthesized as polycrystalline powders from conventional solid-state reactions. Of the materials studied, Ba2SiO4: 0.2% Eu2+ is the most luminous scintillator having a luminosity of 2.7 times the reference material, Bi4Ge3O12. Its scintillation decay curve is comprised of two components with lifetimes of 242 and 668 ns.
