Abstract: Rare earth complex Tb(BA)3phen was synthesized, which is first used as an emitting material in electroluminescence. The properties of monolayer device with the swing film rate of 1000 r·min-1(70 nm) and the weight ratio of 1:5(PVK:Tb(BA)3phen) are the best. And the highest brightness of this device reached 26.8 cd·cm-2 at a fixed bias of 21 V. Bright green emission could be obtained from the optimized double-layer device and the highest EL brightness of the device reached 322 cd·m-2 at the voltage of 22 V.
