| Abstract | The persistent luminescence materials are drawing more and more attentions because of a constantly growing market for their applications. As the new generation of long afterglow phosphors, lanthanide ion doped alkaline earth silicates or aluminates yield much better characteristics, such as longer duration time, brighter luminosity and improved chemical stability, than the conventional sulfide materials used earlier [1]. Although some new materials are already in commercial use, the mechanism of the persistent luminescence are still under discussion, especially the nature of the different hole traps or electron traps and their roles in the luminescence process. In this work, the luminescence from Eu and Dy codoped Sr2MgSi2O7 was investigated under synchrotron radiation excitation as an attempt to shed some light on the luminescence mechanism of this newly developed blue-emitting long afterglow phosphor. |
