Eu2+-activated Ca3MgSi2O8 (Ca3MgSi2O8:Eu2+) phosphors were successfully synthesized by an amorphous metal complex method using propylene glycol-modified silane (PGMS) and heat-treatment under a reduced atmosphere at 1400 °C. The photoluminescence (PL) of Ca3MgSi2O8:Eu2+ was studied as a function of total Eu concentration. Furthermore, Ca3MgSi2O8 with Eu2+ concentrations at 1.0–30 % for Ca exhibited a blue-green emission peaking at approximately 480 nm. In contrast, with increasing Eu2+ concentration up to 50 % for Ca, the emission peak of Ca3MgSi2O8:Eu2+ phosphors exhibited a redshift to 521 nm with green emissions. The redshift of emissions in Ca3MgSi2O8:Eu2+ phosphors could be attributed to the strong electrostatic interactions related to the Eu2+ ions occupying the peculiar Ca sites.
