| titleOfInvention | Method for manufacturing phosphor |
| abstract | Provided is a method for producing a phosphor capable of emitting light in an arbitrary color in a blue to green range based on near-ultraviolet irradiation. SOLUTION: A predetermined amount of each of terbium chloride hexahydrate aqueous solution, cerium chloride heptahydrate and calcium chloride is sampled and diluted (Ce / Ca atomic ratio is 0 to 0.5, Tb / Ca atomic ratio is 0.005-0.5, (Tb + Ce + Ca) / Si atomic ratio is 0.5-2.0 “optimum value 1.0-1.5”), the mixed aqueous solution is stirred for a predetermined time, and sodium metasilicate An aqueous solution obtained by diluting an aqueous solution is quickly added, mixed and filtered to synthesize Ce 3+ , Tb 3+ activated calcium silicate hydrate, and then 800 ° C. to 1,100 ° C. under the atmospheric pressure “optimum value” A heat treatment is performed at a heating temperature of “800 ° C. to 950 ° C.” for a predetermined heating time to obtain Ce 3+ and Tb 3+ co-activated calcium silicate.
