    • The present invention aims at providing a chemically stabilized inorganic phosphor, among oxynitride phosphors including alkaline earths, which oxynitride phosphor emits orange or red light at longer wavelengths at higher luminance than conventional sialon phosphors activated by rare earths. The present invention further aims at providing a light emitting instrument based on the phosphor, for a lighting instrument excellent in color rendering property and for an image displaying apparatus excellent in durability.The solving means resides in provision of a fundamental phosphor comprising:a composition on a pseudo-ternary phase diagram including AO (A is one kind or two or more kinds of element(s) selected from Mg, Ca, Sr, and Ba; and AO is oxide of A), Si3N4, and SiO2 as end members, respectively, and satisfying all of the following conditions:in a composition formula, pAO-qSi3N4-rSiO2(p+q+r=1), 0.1≦p≦0.95  (1), 0.05≦q≦0.9  (2), and 0≦r≦0.5  (3), and at least a metallic element M (M is one kind or two or more kinds of element(s) selected from Mn, Ce, Nd, Sm, Eu, Tb, Dy, Ho, Er, Tm, and Yb) dissolved, in a solid state, in the composition.
    • 本发明的目的是提供一种化学稳定的无机磷光体,其包括碱土金属的氮氧化物荧光体,该氮氧化物荧光体以比由稀土活化的常规硅铝氧氮磷光体更高的亮度发出较长波长的橙色或红色光。 本发明的目的还在于提供一种基于荧光体的发光装置,用于显色性优异的照明装置和耐久性优异的图像显示装置。 解决方案在于提供一种基本荧光体,其包括:包含AO(A是选自Mg,Ca,Sr和Ba中的一种或两种以上元素的伪三元相图中的组合物;以及 AO分别为A),Si 3 N 4和SiO 2的氧化物,并满足以下所有条件:在组成式中,pAO-qSi 3 N 4 -rSiO 2(p + q + r = 1),< -formulae description =“In-line Formulas”end =“lead”?> 0.1 <= p <= 0.95(1),<?in-line-formula description =“In-line Formulas”end =“tail”?> <?in-line-formula description =“In-line Formulas”end =“lead”?> 0.05 <= q <= 0.9(2),<?in-line-formula description =“In-line Formulas”end =“tail”?> <?in-line-formula description =“In-line Formulas”end =“lead”?> 0 <= r <= 0.5(3),<?in-line-formula description = 至少一种金属元素M(M是选自Mn,Ce,Nd,Sm,Eu,Tb,Dy,Ho中的一种或两种以上的元素的直列公式“end =”tail“ ,Er,Tm和Yb)以固态溶解于其中 组成。
