SINGLE CRYSTAL SCINTILLATOR MATERIAL, METHOD FOR PRODUCING SAME, RADIATION DETECTOR AND PET SYSTEM

摘要

A method for producing a single crystal scintillator material, which comprises a step wherein a Ce compound and a Lu compound are mixed into a solvent which contains one or more elements selected from Li, Na, K, Rb and Cs, W and/or Mo, B and oxygen, and then the resulting mixture is heated to a temperature not less than 800°C but not more than 1350°C, thereby melting the compounds, and a step wherein a single crystal represented by the following composition formula: (CexLu1-x)BO3 with a composition ratio x of Ce satisfying 0.0001 = x = 0.05 is grown by deposition by cooling the molten compounds.
