摘要:
A sintered, annealed scintillator composition, which, prior to annealing, has a formula of A3B2C3O12, where A is at least one member of the group consisting of Tb, Ce, and Lu, or combinations thereof, B is an octahedral site (Al), and C is a tetrahedral site (also Al). One or more substitutions are included. The substitutions may may be partial or, in some cases, complete, and can include Al with Sc at B, up to two atoms of oxygen with fluorine and the same number of Ca atoms at A, replacement at B with Mg and the same number of atoms of oxygen with fluorine, replacement at B with a combination of Mg/Si Mg/Zr, Mg/Ti, and/or Mg/Hf, replacement at B with a combination of Li/Nb and/or Li/Ta, and at A with Ca and replacement of an equal number of B or C with silicon.
