摘要：

The Eu2+ and Dy3+ codoped silicates, Ca2MgSi2O7: Eu2+, Dy3+, was synthesized, and its photoluminescence properties were studied with synchrotron radiation. Under synchrotron radiation excitation at 305 nm, only the characteristic emission from Eu2+ was excited. But the characteristic emission from Dy3+ was also found under 175 nm excitation, besides the characteristic emission of Eu2+. The characteristic emission from Dy3+ was detected in the Eu2+ and Dy3+ codoped long lasting phosphorescence materials, which indicates that Dy3+ is still existed in the phosphors under continue excitation at 175 nm.
