摘　　要：We report the luminescence properties and decay profiles of Ce：YAlO3, Mn：YAlO3, and Ce,Mn：YAlO3 crystals grown by Czochralski method. The spectroscopic properties show that both Mn2＋ ions and Mn4＋ ions exist in Mn：YA103 and Ce,Mn：YAlO3 crystals. The Mn2＋ ions have a broad emission band of 60 nm in Mn-doped YAlO3 crystal at 530 nm. The luminescence spectra also indicate that there is significant energy transfer between Ce3＋ and Mn4＋ in Ce,Mn：YA103 crystal. Because of the energy transfer, the first decay component in Ce,Mn：YAlO3 decreases from 24.5 to 10.8 ns, which is much faster than that of Ce：YAlO3.We report the luminescence properties and decay profiles of Ce：YAlO3, Mn：YAlO3, and Ce,Mn：YAlO3 crystals grown by Czochralski method.
