| titleOfInvention | Yellow phosphor and method for producing the same |
| abstract | An object of the present invention is to provide a phosphor having high emission intensity (luminance) at normal temperature and little deterioration in emission intensity (luminance) even when exposed to high temperatures, and a method for producing the same. A Si / Ge water-solubilization step in which a polyol compound and a Si alkoxide compound and / or a Ge alkoxide compound are mixed and heated in the presence of an acid catalyst to obtain a water-soluble Si compound and / or a water-soluble Ge compound ( 1) and a first element selected from at least one selected from alkali metals, a second element selected from at least one selected from Ca, Sr and Ba, a rare earth element selected from at least one selected from Bi and Mn Yellow fluorescence including a raw material aqueous solution preparation step (2) in which an aqueous solution containing three elements and the water-soluble Si compound and / or the water-soluble Ge compound are mixed, and a gelation step (3) in which the raw material aqueous solution is heated. It is a manufacturing method of a body. [Selection figure] None |
