Red-emitting Europium( ) doped SrAl2B2O7 phosphors have been prepared by precipitation method, and its luminescent properties under UV excitation have been investigated. The phosphors are characterized by x–ray diffraction (XRD) and photoluminescence spectra. The SrAl2B2O7:Eu3+ phosphors can be obtained at 900 by calcining precipitation precursor. These phosphors can be effectively excited by UV light at 394nm. In emission spectra, the strongest peak at 618 nm correlating to red emission is due to the electric dipole transition 5D0 7F2 of Eu3+ ions. The luminescent properties of SrAl2B2O7:Eu3+ phosphors with 8 mol% doping concentration of Eu3+ are optimal.
