Abstract Twenty one doped SrAl₂O₄ long after-glowed phosphors with 4 series were synthesized by self-propagating high-temperature synthesis method (SHS) with urea-nitrate solution which served as media at 600 ℃. They are SrAl₂O₄∶Eu²⁺_{0.012 5}, RE³⁺_{0.012 5}(RE³⁺=Ce³⁺, Pr3+, Nd³⁺, Tb³⁺, Dy³⁺), SrAl₂O₄∶Eu²⁺_{0.012 5}, M_{0.012 5}(M=Li⁺, Be²⁺, Cd²⁺, Mn²⁺, Cu²⁺, Ag⁺, Zn²⁺, Pb²⁺), SrAl₂O₄∶Eu²⁺_{0.012 5}, Dy³⁺_{0.012 5}, M_{0.012 5}(M=Mn²⁺, Cu²⁺, Ag⁺, Zn²⁺), and SrAl₂O₄∶Eu²⁺_{0.012 5}, Dy³⁺_{0.012 5}，RE3+_{0.012 5}(RE³⁺=Ce³⁺, Pr³⁺, Nd³⁺, Tb³⁺), of which luminescence and after-glowing features were tested. The morphology of all these samples presents a state of porosity and laxity. The samples show an intense emission peak at 514 nm and broad peaks of the excitation spectra at 290～360 nm, Tb³⁺ and Dy³⁺ had most effects on luminance and after-glowed time respectively. The SrAl₂O₄∶Eu²⁺_{0.012 5}, Dy³⁺_{0.012 5} had good luminance and proper after-glowed time as well.
