In this paper, preparation and characterization of green long afterglow phosphors SrAl2O4：Eu^2＋,Dy^3＋ as an new integrated experiment is introduced. The experiment is based on sol - gel method and basic chemical operation. Besides t test of its structure （ X - ray diffraction ）, morphology（scamping electron microscopy）, excitation spectrum and emission spectrurn etc. is also included. The result proves that it is a typical integrated experiment for juniors to learn soft chemistry and the technique of material preparation.
