摘要Eu3+ doped CaMoO4 phosphors were synthesized by using the solid state reaction method. The x−ray diffraction shows that all the patterns of the obtained samples are indexed to the sheelite structure. Red afterglow originating from the 5D0–7FJ (J=0,1,2,3,4) transitions of Eu3+ was observed after the samples were excited by 254 nm and the optimal Eu3+ concentration in the CaMoO4 matrix was experimentally determined to be 0.50%. A possible explanation of this afterglow property is also discussed.
