| 简介 |
An objective is to provide a manufacturing process of a rare earth activated alkaline earth metal fluorohalide stimulable phosphor exhibiting improved productivity accompanied with an X-ray resistance property against repeating use upon X-ray exposure. Disclosed is a liquid phase manufacturing process of a rare earth activated alkaline earth metal fluorohalide stimulable phosphor represented in following Formula (1) possessing the steps of adding an aqueous solution containing inorganic fluoride into a reaction mother liquor in which barium halide is dissolved at a reaction temperature of 85 - 100 °C, to form a crystalline precipitate of a precursor of a rare earth activated alkaline earth metal fluorohalide stimulable phosphor, and removing a solvent from the reaction mother liquor, wherein a precursor of a stimulable phosphor is prepared via the foregoing steps conducted in parallel. €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒFormula (I)€ƒ€ƒ€ƒ€ƒ€ƒBa (1-x) M 2 (x) FBr (y) I (1-y) : aM 1 , bLn, cO |
