    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 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.

    摘要: Disclosed are oxynitride phosphor compositions having the formula (RE1-xCex)3Ala-y-z-wSiyGazScwO12-yNy, where RE is at least one of Lu, Gd, Y, and Tb, 0.001≦x≦0.10, 0≦w≦2, 0.001≦y≦0.50, 0≦z≦4.999, and 4.5≦a≦5.0. When combined with radiation from a blue or UV LED, these phosphors can provide light sources with good color quality having high CRI over a large color temperature range. Also disclosed are blends of the above oxynitride phosphors and additional phosphors.
