| Abstract: | The Sr3MgSi2O8:Eu2+ samples with different NH4Cl(as flux) content and different Eu2+ concentration were prepared by the solid-state reaction.The phase purity and luminescence properties of samples were studied.The results indicate that the sample is single phase with highest luminescence intensity,while the content of NH4Cl is 24%.The strong excitation band of the sample is in the NUV region (250-400 nm),peaked at 366 nm.Corresponding emission band is in the blue region(420-500 nm),peaked at 457 nm.This ban... |
