The Eu3+-doped Na24As2W22O83 phosphor has been prepared by solid state reaction from Na3AsO412H2O,Na2WO4@2H2O and WO3, and characterized by elemental analysis, infrared spectroscopy and powder X-ray diffractometry.According to the measurements with X-ray diffraction, this material belongs to orthorhombic system with its lattice con-stants: a = 1.4750 nm, b = 1.1944 nm, c = 1.1062 nm, it is consistent with space group D24-P212121 (No.19). The emissionand excitation spectra were measured. The luminescent properties of Eu3+-doped Na24As2W22O83 and mechanism of energytransfer were discussed.
