ABSTRACT:
A green-light-emitting phosphor of a high emission brightness when excited by blue light emitted from a blue LED is provided. The green-light-emitting phosphor is represented by a formula M1-aSi2O2-1/2nXnN2:Eua, wherein M is at least one element of strontium (Sr), barium (Ba) and calcium (Ca); X is at least one element of chlorine (Cl) and bromine (Br); a is 0.005≦a≦0.15 and n is 0.02≦n≦0.2. Substitution of a part of the oxygen (O) in a matrix with at least one halogen element of chlorine (Cl) and bromine (Br) gives a green-light-emitting phosphor of higher brightness.
