摘要：

Eu3+ and Dy3+ as activators in luminescence materials have been widely investigated because of their superior luminous properties. In this work, we synthesize Sr2MgSi2O7:Dy3+, Sr2MgSi2O7:Eu3+, and Sr2MgSi2O7:Eu3+, Dy3+ in air via the solid-state reaction method. We research crystal phase and purity of all samples via XRD, discern their crystal structure and space-group, and investigate their luminescence properties. The yellow emission of Sr2MgSi2O7:Dy3+ with emission spectrum in the range of 450-775 nm can be observed due to the F-4(9/2) -> H-6(15/2), H-6(13/2), H-6(11/2), and H-6(9/2) transitions of Dy3+ ion. The red emission of Sr2MgSi2O7:Eu3+ in the range of 550-725 nm is shown owing to the D-5(0) -> F-7(1), F-7(2), F-7(3), and F-7(4) transitions of Eu3+ ion. Sr2MgSi2O7:Eu3+, Dy3+ under excitation 388 nm shows yellow emission with chromaticity coordinates (0.3578, 0.3911) and glows red-orange light with chromaticity coordinates (0.5753, 0.3863) under excitation 394 nm. Sr2MgSi2O7:Eu3+, Dy3+ can shows tunable emission when the ratio between Eu3+ and Dy3+ ions is changed. The energy transfer from Dy3+ to Eu3+ ions are known via the spectral features. Sr2MgSi2O7:Eu3+, Dy3+ has a good thermal stability. Luminous mechanisms and energy transfer process of samples are analyzed by the energy level diagrams of Dy3+ and Eu3+ ions.
