| Abstract: | A method for the rapid preparation of green long afterglow phosphors SrAl2O4-Eu^2＋,Dy^3＋ was established. With citric acid, strontium nitrate, aluminum nitrate and europium nitrate,etc as raw materials,the rapid preparation was achieved. The time of preparation of long afterglow phosphors SrAl2O4： Eu^2＋, Dy^3＋ could be shorten the time to under 12 hours by improvement experiment. The synthesized products were characterized by X ray diffraction,scanning electron microscopy and spectrum analysis, etc. The prepared sample by the method is tended to be consistent with the traditional sol-gel method. |
