Abstract：
 A photoluminescent spherical porous ceramic material with ultra-long afterglow is prepared through proportioning raw materials, stirring, drying, pre-calcinining, adding disperser solution, spray granulating, drying and calcing in reduction atmosphere. Its advantages are high looseness, light absorption and hydrolysis resistance, and long afterglow (20hr).
