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 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. Related devices are also described, such as CT scanners and well-logging devices.
A sintered, annealed scintillator composition comprising, prior to annealing:
A CT scanner which includes a detector element, wherein the detector element comprises a sintered, annealed scintillator composition which itself comprises, prior to annealing, a garnet having a formula of A3B2C3O12, where A is a site with 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), with at least one substitution selected from the group consisting of:
A radiation detector for detecting high-energy radiation, comprising:
