The luminescence properties and the energy transfer between Eu^2+ and Mn^2+ are investigated. The emission bands of this phosphor peaked at 42Ohm and 67Ohm are originated from the 5d → 4f transition of Eu^2+ and from the 4T1 (4G) --〉 6A1 (6S) transit/on of Mn^2+, respectively. With the increasing Mn^2+ concentration, the intensity of fixed concentra- tion Eu^2+ decreases and the intensity of Mn^2+ also increases. It is suggested that there is an energy transfer from Eu^2+ to Mn^2+ in SrZnP2O7 host. According to Dexter's energy transfer formula of multipolar interaction, the energy transfer between Eu^2+ and Mn^2+ is due to the electric dipole-quadrupole interaction of the resonance transfer. %K 78 %K 55 %K -m %K 33 %K 50 %K Dq %K 34 %K 30 %K +h
