A series of Ca2.955-xMxSi2O7: 0.045Eu2+ (M= Sr, Ba, x= 0.10.5) phosphors is prepared by solid-state reaction method. The influences of Sr or Ba with larger radius substitution on the structure and luminescence properties for Ca2.955Si2O7: 0.045Eu2 + phosphor are investigated. The XRD results show that a small quantity of Sr or Ba substitution of Ca does not change the structure of Ca3Si2O7 host which has a monoclinic crystal structure. Before the substitution, the emission peak is at about 574 nm. If the Ca2+ ions are substituted by Sr2+ or Ba2+ ions, the emission peak is blue shifted when the Sr or Ba concentration is 0.5. In addition, for the same doping contents of Sr and Ba, the Ba doped phosphors have stronger emission intensity.
