Abstract: Rare earth complex TbY(m-MOBA)6(phen)2·2H2O was synthesized,which was first used as an emitting material in electroluminescence.The properties of monolayer device with the rate of 1000 r·min-1 (70 nm) and the impure concentration of 1∶5 were the best.And the highest brightness of this device reached 21.8 cd·cm-2 at a fixed bias of 20 V.Bright green emission can be obtained from the optimized double-layer device,and the highest EL brightness of the device reached 289 cd·m-2 at the voltage of 21 V.
