摘要: Abstract Divalent europium activated tristrontium dialuminum hexaoxide phosphor, (Sr 1- x Eu ) 3 Al 2 O 6 , was obtained by solid state reaction. Crystal structure and luminescence properties of synthesized were investigated. The major excitation band located in blue light region, the photoluminescence spectrum showed red emission peaked at 618 nm which could be attributed to d-f transition 2+ . influence Ca substitution for Sr on structural doped also studied. peak position y 2.94 0.06 varied from 655 with increasing value. reason redshift phosphor discussed.
