abstract = "New blue-emitting phosphor, SrCa2MgSi2O8:Eu2+ (SCMSO:Eu2+), was synthesized by a solid state reaction. For further discussion, a series of analysis were performed such as photoluminescence excitation and emission spectra, diffuse
reflectance spectra, thermal quenching, decay lifetime and electroluminescence to identify the luminescent properties of SrCa2MgSi2O8:Eu2+ phosphors. The SCMSO:Eu2+ displays broad excitation spectra ranging from 250450 nm, and intend
emission intensity at 469 nm under 
ex = 360 nm. The optimum Eu2+ concentration of SCMSO was 10 mol%. The luminescence decay lifetimes of SCMSO:Eu2+ phosphors were measured to be 474.1540.4 ns. The blue-emitting SrCa2MgSi2O8:10%Eu2+
phosphors fabricated with commercial red- and green-emitting phosphor integrating white LED, excited with near UV LED chip (
ex = 390 nm), and shows excellent color rendering index. In this study, the results obtained highly indicates that SCMSO:Eu2+ is
potentially blue-emitting phosphor for application in white LEDs.",
