摘 要：Divalent europium activated tristrontium dialuminum hexaoxide phosphor, （Sr1-xEux）3Al2O6, was obtained by solid state reaction. Crystal structure and luminescence properties of synthesized （Sr1-xEux）3Al2O6 were investigated. The major excitation band of （Sr1-xEux）3Al2O6 located in blue light region, the photoluminescence spectrum showed red light emission peaked at 618 nm which could be attributed to the d-f transition of the Eu2+. The influence of Ca2+ substitution for Sr2+ on structural and luminescence properties of Eu2+ doped Sr3Al2O6 was also studied. The photoluminescence peak position of （Sr1-yCay）2.94Eu0.06Al2O6 varied from 618 to 655 nm with increasing y value. The reason for redshift in the emission band of （Sr1-yCay）2.94Eu0.06Al2O6 phosphor was also discussed.
