Organic Light Emitting Devices Based on Terbium Complex

摘要

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.
