Serpentine is a hydrated ultra-mafic rock, which is primarily composed of magnesium silicate minerals such as chrysotile and antigorite. Fibrous chrysotile is the most common type of asbestos. Since the rich mines supplied serpentine in Japan, application of natural ore "serpentine" as raw materials for ceramics has one of the potentially lowest cost ceramics production. In this study, long afterglow phosphor, Sr_2MgSi_2O_7, has been successfully synthesized using natural ore serpentinite. Eu^<2+> and Dy^<3+> co-doped compounds show long-lasting phosphorescence. This demonstrates that the "serpentine" could be used in preparing alkaline earth silicate phosphors.
