Abstract：Rare earth complex Tb(BA)3phen has been synthesized, which is used as an emitting material in electroluminescence. The properties of monolayer device with the rate of 1 000 r·min-1 and the impure concentration of 1∶5 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 can be obtained from the optimized double-layer device and the highest EL brightness of the device reaches 322cd·m-2 at the voltage of 22V.
