Abstract: A light-emitting device is produced using a phosphor composition containing a phosphor host having as a main component a composition represented by a composition formula: aM3N2.bAlN.cSi3N4, where “M” is at least one element selected from the group consisting of Mg, Ca, Sr, Ba, and Zn, and “a”, “b”, and “c” are numerical values satisfying 0.2≦a/(a+b)≦0.95, 0.05≦b/(b+c)≦0.8, and 0.4≦c/(c+a)≦0.95. This enables a light-emitting device emitting white light and satisfying both a high color rendering property and a high luminous flux to be provided.

Abstract: A chip-type light-emitting semiconductor device includes: a substrate 4; a blue LED 1 mounted on the substrate 4; and a luminescent layer 3 made of a mixture of yellow/yellowish phosphor particles 2 and a base material 13 (translucent resin). The yellow/yellowish phosphor particles 2 is a silicate phosphor which absorbs blue light emitted by the blue LED 1 to emit a fluorescence having a main emission peak in the wavelength range from 550 nm to 600 nm, inclusive, and which contains, as a main component, a compound expressed by the chemical formula: (Sr1-a1-b1-xBaa1Cab1Eux)2SiO4 (0≦a1≦0.3, 0≦b1≦0.8 and 0
