摘要The SrZnP2O7:Eu2+, Mn2+ phosphor is synthesized by high temperature solid state reaction. The luminescence properties and the energy transfer between Eu2+ and Mn2+ are investigated. The emission bands of this phosphor peaked at 420nm and 670nm are originated from the 5d→4f transition of Eu2+ and from the 4T1 (4G) →6A1 (6) transition of Mn2+, respectively. With the increasing Mn2+ concentration, the intensity of fixed concentration Eu2+ decreases and the intensity of Mn2+ also increases. It is suggested that there is an energy transfer from Eu2+ to Mn2+ in SrZnP2O7 host. According to Dexter's energy transfer formula of multipolar interaction, the energy transfer between Eu2+ and Mn2+ is due to the electric dipole-quadrupole interaction of the resonance transfer.
