A novel luminous phosphor SrAl2O4: Eu2+, Dy3+/Sr2MgSi2O7:Eu2+, Dy3+/light conversion agent with both red luminescence characteristics and persistent luminescent performance were prepared. According to the intermediary color law, the color purity of red emission can be controlled by the doping ratio of SrAl2O4: Eu2+, Dy3+ in SrAl2O4: Eu2+, Dy3+/Sr2MgSi2O7: Eu2+, Dy3+ composite luminous material. The anticipated luminescence properties could be realized precisely by adjusting the ratio. The microscopic morphology of the composite material, energy dispersive spectrometer, X-ray diffraction, FT-IR spectra, emission spectrum, CIE chromaticity diagrams and afterglow properties were examined. The brief outlines about some phenomena aspects and detailed physical descriptions as well as manuals were available. From the analyses of CIE chromaticity diagrams and afterglow properties, the doping ratio of SrAl2O4: Eu2+, Dy3+/Sr2MgSi2O7: Eu2+, Dy3+ can influence afterglow brightness and red emission purity. The samples show great optical performance.
