JIANG Ling, CHANG Cheng-Kang, MAO Da-Li (School of Materials Science and Engineering, Shanghai Jiaotong University, Shanghai 200030, China)  
Long lasting alkaline aluminate phosphorescent materials have become a new kind of energy storing materials because of their excellent luminescent properties. This paper reviewed the recent progress on the research in this field. The luminescence characteristics and the long lasting phosphorescent properties of the materials were summarized and new methods for the preparation of the materials were summed up in detail. Two different mechanisms of the afterglow behavior were discussed, then the new research direction and latent application fields were pointed out.
