The long lasting phosphorescent materials composing of alkaline earth aluminates, which were found in 1990s, are a kind of important energy power and saving energy materials. Due to potential widespread application as night display materials and unique advantages in safety and environmental protection and stabilization over the precursors, such as, zinc sulfide and alkaline earth sulfides, research on the materials has attracted much interest. Recent developments on the long lasting phosphorescent materials are reviewed in present paper. The characteristics and advantages of the long lasting phosphorescent materials with oxide composition are pointed out. The kinds and natures of hosts and activators which compose the long lasting phosphorescence materials and their effect on the phosphorescent properties are summarized. The mechanism or model of the long lasting phosphorescence is generalized. Future development aspects of researchs and applications about the materials are proposed.
