Phosphor plate and light-emitting device
A phosphor plate (100) according to the present invention is a phosphor plate having a plate-shaped composite comprising a base material and an alpha-sialon phosphor present in the base material, and in an X-ray diffraction analysis pattern using a Cu-K alpha ray, the alpha-sialon phosphor has an alpha-sialon structure and an alpha-sialon structure, and the alpha-sialon phosphor has an alpha-sialon structure and an alpha-sialon structure. When I [alpha] is the peak intensity corresponding to the alpha-sialon phosphor in the range of the diffraction angle 2 [theta] of 30.2 DEG to 30.4 DEG and I [beta] is the peak intensity of the peak in the range of the diffraction angle 2 [theta] of 26.6 DEG to 26.8 DEG, I [alpha] and I [beta] satisfy 0 < I [beta]/I [alpha] < = 10.
本发明的荧光体板(100)是具有板状的复合体的荧光体板，该板状的复合体包含母材和存在于母材中的α型赛隆荧光体，在使用Cu－Kα射线的X射线衍射分析图案中，在将衍射角2θ为30.2°～30.4°的范围内的与α型赛隆荧光体对应的峰强度设为Iα并将衍射角2θ为26.6°～26.8°的范围内的峰的峰强度设为Iβ时，Iα、Iβ满足0＜Iβ/Iα≤10。
