摘要：
An LED light emitting device is provided that has high color rendering properties and is excellent color uniformity and, at the same time, can realize even luminescence unattainable by conventional techniques. A phosphor having a composition represented by formula: (Sr2-X-Y-Z-ωBaXMgYMnZEuω)SiO4 wherein x, y, z, and ω are respectively coefficients satisfying 0.1 z, and 0.01
