摘要：

Rare earth ions doped CaMgSi2O6 photo-luminescent materials with long afterglow were prepared by solid state reaction in a reductive atmosphere. The influence of co-doping rare earth ions (Dy and Nd) on the luminescence of CaMgSi2O6 host was studied. The 438 nm emission of the phosphors can be ascribed to 4f(7)-4f(6)5d interconfiguration transitions of Eu2+ ions, which is caused by the [EuO6] emitting center formed in CaMgSi2O6 host. All of these phosphors have long afterglow phenomenon. Both afterglow intensity and persistent afterglow time of CaMgSi2O6:Eu, Dy are better than those of CaMgSi2O6:Eu and CaMgSi2O6:Eu, Nd, which is in agreement with the results of thermally stimulated luminescence curves.
