SiO2, CaO and MgO was chosen as main raw material and Solid State method was used to prepare the samples. The precursor was directly sintered at 1000℃for 3h to obtain new green CaMgSi2O6:Eu3+,Li+Phosphors.The effects of the content of the doping ions Eu3+ on the luminescent properties have been studied. The structure, morphology and luminescent properties of the phosphors were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM),UV and PL-PLE spectra respectively.The results showed that the CaMgSi2O6:Eu3+,Li+ was base-centered monoclinic crystals, the phosphor particle distributed uniformly.The phosphor has a strong absorptive capacity excited by 248 nm ultraviolet ray, and could emit the strong red light with the wavelength of 590nm(5D0→7F1)and 615nm(5D0→7F2). The CaMgSi2O6:Eu3+,Li+ is a new type of red fluorescent material.
