摘要： A ceramic scintillator material consists of a sintered body of a rare earth oxysulfide phosphor containing Pr as an activator. The sintered body has a texture where coarse grains of irregular polyhedron and slender fine grains are intermixed. The coarse grains have a shape of for instance a dimension (average value) in the range of 50 to 100 &mgr;m, the fine grains having a shape of which average short axis is in the range of 2 to 5 &mgr;m and average long axis in the range of 5 to 100 &mgr;m. An area ratio of the coarse grains to the fine grains is in the range of 10:90 to 60:40. Such a ceramic scintillator material has, in addition to excellent light output (high sensitivity), mechanical strength capable of coping with downsizing of a detector. Furthermore, non-uniformity in sensitivity that causes artifacts can be decreased.

摘要： A sintered body of a rare earth oxysulfide is heat-treated at a temperature of 900° C. to 1200° C. in an atmosphere of a mixture of sulfur and oxygen to form island-like rare earth oxide phases on the surface of the sintered body to produce a ceramic scintillator. Therefore, the ceramic scintillator comprises a sintered body of a rare earth oxysulfide, and a rare earth oxide phase formed on the surface of the sintered body, wherein a rare earth oxysulfide phase or the rare earth oxide phase is dispersed on the surface of the sintered body, so that the optical output characteristic of the ceramic scintillator is improved. According to this ceramic scintillator, it is possible to remove the pressure and distortion during sintering, the coloring caused by the deviation from the stoichiometric composition, and the coloring caused during processing such as saw-cutting and polishing.
