Patent ID: 6939480

Claim:
A method of manufacturing a phosphor of any one of MeMgSi 2 O 6 :Eu and Me 3 MgSi 2 O 8 :Eu wherein Me comprises at least one of Ca, Sr, and Ba with an average diameter ranging from 0.1, to 3.0 μm, the method comprising: preparing a mixed solution by mixing a material and an aqueous medium; preparing a hydrate by mixing the mixed solution and an alkaline base; preparing a precursor by performing a hydrothermal synthesis reaction on a solution containing the hydrate and water therein at temperatures ranging from 100 to 300° C. under pressures ranging from 0.2 to 10 MPa; and baking the precursor at temperatures ranging from 800 to 1400° C. in a reducing atmosphere.
