  ABSTRACT: Synthesis of oxynitride solid solutions CaAl4-xSixO7-xNx:Eu2+ (x = 0 - 4) was attempted by the solid state reaction (SSR) methods using Si3N4 and AlN as nitrogen sources. The Ca3Al8Si4O17N4 (x = 4/3) sample with the high phase purity was obtained when AlN was used as a nitrogen source whereas the sample synthesized using Si3N4 as another nitrogen source contained a Ca2Al2SiO7 impurity. Thus, it was revealed that AlN was a preferable nitrogen source for the synthesis of Ca3Al8Si4O17N4 by the SSR method. The solid solutions around x = 4/3 activated with Eu2+ exhibited bluish-green luminescence with emission maxima at 480 nm by the excitation at 250 - 450 nm. Thus, the CaAl4-xSixO7-xNx: Eu2+ solid solutions especially for Ca3Al8Si4O17N4:Eu2+ (x = 4/3) were developed as novel Eu2+
