White light-emitting materials of Eu2+, Mn2+-codoped Ca2SiO3Cl2 were prepared. Luminescence properties and other samples phase were tested by X-ray diffraction (XRD) and fluorescence spectrophotometer (PL). The results showed that the temperature range of 730°C to 760°Cand the ideal holding time is 4h~5h, the emission spectrum of Eu2+-doped sample under excitation at 365nm wavelength was 426nm, 524nm in a weak reductive atmosphere of active carbon, the emission spectrum of Eu2+, Mn2+ co-doped samples was 426nm, 524nm, 585nm, the three combined can produce white light.
