| description | A surface-coated phosphor particle of the invention comprises a particle containing a phosphor and a coating section that coats the surface of the particle, wherein the phosphor has a predetermined composition, the coating section forms at least a portion of the outermost surface of the particle and contains AlF3, and in an X-ray diffraction pattern of the surface-coated phosphor particle measured using a Cu-K[alpha] beam, if the light emission intensity of a maximum peak A for which 2[theta] is within a range from 23DEG to 26DEG is deemed IA, and the light emission intensity of a maximum peak B for which 2[theta] is within a range from 36DEG to 39DEG is deemed IB, then IA and IB satisfy IA/IB ≤ 0.10. |
