摘要
A series of Ce3＋, Tb3＋ or Ce3＋/Tb3＋ doped YA13（BO3）4 phosphors are synthesized by a high temperature solid-state reaction, and their luminescent properties are investigated. YA13（BO3）a：Ce3＋ shows a broad emission band at 422 nm under the 367 nm radiation excitation. YA13（BO3）4：Tb3＋ can be efficiently excited by the ultraviolet （UV） light, and produces green emission. The emission intensity of YA13（BO3）4：Tb3＋ can be enhanced by adjusting Tb3＋ doped content, and reaches the maximum at 0.06 mol Tb3＋. When Ce3＋ is codoped, the emission intensity of Tb3＋ in YA13（BO3）4 can be enhanced, but the commission international del＇eclairage （CIE） chromaticity coordinates of YA13（BO3）4：Tb3＋ have almost no change. Moreover, the energy transfer from Ce3＋ to Tb3＋ in YA13（BO3）4 is studied.
