【Abstract】 Current research progress in silicate-based long afterglow phosphorescent materials doped with rare earth ions is reviewed in this paper. The kinds and characteristics of the phosphorescent materials are summarized. Their chemical compositions, crystal structures, their effects on luminescent properties, their luminescent mechanisms and synthesis methods are discussed, respectively. Based on present research and application status, the prospects of studies and applications of the silicate based phosphors are proposed.更多还原
