A series of Dy3+ - Eu3+ co-doped BaAl2Si2O8 phosphors were prepared via the conventional solid-state reaction method. Their crystal structure, luminescent characteristic and lifetime were investigated. The optimum doping concentrations of Dy3+and Eu3+ are both 0.05 for Dy3+ or Eu3+ singly doped BaAl2Si2O8. Furthermore, BaAl2Si2O8: 0.05Dy3+ and BaAl2Si2O8: 0.05Eu3+ emits yellow and red light. The emission...
