Abstract Disclosed are an oxynitride phosphor and a light-emitting device which are improved in luminous efficiency and emission intensity. A SiAlON phosphor (7) is composed of an oxynitride phosphor represented by the general formula of CaX(Si,Al)12(O,N)16: Eu<2+>y wherein x is not less than 0.75 and not more than 1.0 and y is not less than 0.04 and not more than 0.25. The main phase of the oxynitride phosphor has an alpha-sialon crystal structure. Sont révélés ici un luminophore à oxynitrure et un dispositif d'émission de lumière qui voient leur rendement lumineux et leur intensité d'émission améliorés. Un luminophore SiAION (7) est composé d'un luminophore à oxynitrure représenté par la formule générale CaX(Si,Al)12(O,N)16: Eu<2+>y où x n'est pas inférieur à 0,75 et pas supérieur à 1 et y n'est pas inférieur à 0,04 et pas supérieur à 0,25. La phase principale du luminophore à oxynitrure à une structure cristalline SiAlON alpha.
