The intermediate role of Gd3+ in energy transfer to give light was investigated through spectroscopic study of Bi3+/Eu3+ doped YBO3/(Y,Gd)BO3 under VUV/UV excitation. All samples were prepared by solid-state reaction and the luminescent properties were characterized in a synchrotron radiation instrument. The results show that Gd3+ plays an intermediate bridge between the sensitizer of BP3+ and the activator of Eu3+ in energy transfer in (Y,Gd)BO3:Bi3+,Eu3+ system. At the same, the mechanism for energy transfer was discussed, which is mainly through electric multipole interaction or exchange interaction. (C) 2008 Elsevier B.V. All rights reserved.
