A blue-emitting phosphor is optimized by controlling mole fractions typically of Mg and Si in Sr<SUB>3-e</SUB>Mg<SUB>b</SUB>Si<SUB>2</SUB>cO<SUB>8d</SUB>:Eu<SUB>e </SUB>or by further including an optimal amount of at least one additional component such as Ba or Ca. The resulting phosphor exhibits a higher brightness and a higher color purity upon excitation by ultraviolet light emitted as a result of discharge of xenon gas. The optimized phosphor is incorporated into light emitting devices such as lamps and PDPs, and further into display devices.
