phosphors were synthesized at 1 200 ℃ by conventional solid state reaction method and their luminescent properties were investigated. Structural characterization of the luminescent materials was carried out with X-ray powder diffraction (XRD) analysis. XRD results showed that no apparently structure transformation of the Sr

the introduction of charge compensator Na

can lead to the strongly enhanced emission intensity of Eu

. Therefore
the material could be a promising red phosphor for possible applications in the white LED.
