| Abstract: | The BaMgAl10O17：（Eu2＋,Mn2＋） phosphors were synthesized by high temperature solid-reaction method.The luminescence performance of these phosphors was investigated,and the probabilities of energy transfer in Eu2＋ and Mn2＋ co-doped system are calculated with the help of Forster-Dexter Theory.The results can well explain the energy transfer phenomena happened in BaMgAl10O17：（Eu2＋,Mn2＋） system.The Eu2＋→Mn2＋ energy transfer by dipole-quadruple interaction is dominated in doped Forster-Dexter system. |
