| titleOfInvention | Green light emitting phosphor, fluorescent material sheet, and light emitting device |
| abstract | PROBLEM TO BE SOLVED: To provide a green emitting phosphor, a phosphor sheet, and a light emitting device having good reliability in a high temperature and high humidity environment. SOLUTION: A powder having the following formula ( Ba , Sr, Eu) SO 3 is obtained by dropping a sulfite into a solution containing a barium compound, a europium compound and a strontium compound, and then the powder. and mixing the powdered gallium compound, then, subjected to primary firing, further, obtained by secondary baking, the following equation, Sr x Ba y Ga 2 S 4: Eu z ( however, x> 0, It is a green luminescent phosphor represented by (y> 0, z> 0, x + y + z = 1).
