| titleOfInvention | Method for producing rare earth activated barium fluorohalide phosphor precursor |
| abstract | The present invention provides a rare earth-activated barium fluoride halide phosphor precursor having a relatively high iodine content, a method for producing the same, and the phosphor. A barium compound, a halogen X compound, an iodide, a rare earth compound, and, if necessary, an alkaline earth metal compound and an alkali metal compound are dissolved in an aqueous medium, and a ratio of an iodine ion concentration to a halogen X ion concentration is set. Preparing a reaction mother liquor having a ratio of 0.30 or more and 10 times or more of the b / 1-b ratio; adding an aqueous solution of fluoride to the reaction mother liquor, and adding a rare earth activated halogen fluoride in the reaction solution A method for producing an iodine-containing rare earth-activated barium fluorohalide phosphor precursor comprising: precipitation of a barium fluoride phosphor precursor; and separation of the phosphor precursor from a reaction solution. [Selection figure] None |
