The homogeneous sedimental mixture of SrC2O4, Al(OH)3 and Eu(OH)3 has been prepared by chemical coprecipitation applying two kinds of precipitant oxalic acid and ammonia. With this coprecipitate monophase SrAl2O4:Eu2+ phosphor has been synthesized at lower temperature 1　100℃. The excitation and emission spectra as well as phosphorescence time of the phosphor are reported.
