Abstract
A novel rare earth complex Eu0.5La0.5(TTA)3phen, displaying electroluminescent property, was synthesized, and monolayer and double-layer devices were fabricated by doping it into poly N-vinylcarbazole. The characteristics of these optimized devices were investigated, and the emitting mechanism was explained through the energy band diagram. Optimized double-layer devices with a turn-on voltage of 6.5 V were achieved. At the current density of 68.48 mA·cm−2, the maximum brightness and the current efficiency of the device reached 238.4 cd·m−2 and 0.35 cd·A−1, respectively.
