M is at least one element selected from the group consisting of La, Y, Tb and Lu. And w, x, y, and z satisfy 2.0<w<4.0, 2.0<x<3.5, 0<y<1.0, and 0<z<2.0, respectively. The phosphor can be efficiently excited by light in a range from near-ultraviolet to blue light, and emit light having components that widely extend mainly from green range to yellow range. A light-emitting apparatus includes the phosphor together with a light-emitting device that emits light in a range from near-ultraviolet to blue light, and can have improved light emission efficiency, good color rendering property, and good color reproduction range. In the case where a light-emitting apparatus includes an additional phosphor, it is possible to further improve its light emission spectrum."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Phosphor, light-emitting apparatus including the same, and phosphor production method","description":"A phosphor is provided which is represented by the general formula MxCeySi6-zBzN8+w.
