More Information
Summary:The present invention relates to phosphor, a light-emiting device and a method for producing phosphor. The embodiment of the present disclosure provides a yellow light-emitting phosphor represented by the formula (1): ((Sr p M 1-p) 1-x Ce x) 2y Al z Si 10-z O u N w. In the formula, M is at least one of the alkaline earth metals, and p, x, y, z, u and w are numbers satisfying the conditions of 0 p 1, 0<x 1, 0.8 y 1.1, 2 z 3.5, 0<u 1, 1.8 z-u and 13 u+w 15. The emission peak of the phosphor shifts within a range of less than 15 nm when the peak of exciting light is changed in the range of 350 to 475 nm.
