摘 要: 以新的稀土红色荧光络合物— Eu( TTA) m 复合体系作为发光层 ,用不同载流子传输材料充当电子传输层做成双层器件 ,研究了双层器件的电致发光特性。对于空穴传输材料 ,高场下器件的电流表现为体内电阻限制 ;而对于电子传输材料 ,器件的电流表现为电极限制。从光谱的变化 。 Organic bilayer electroluminescence devices were fabricated by using a novel Eu (TTA)m complexes as active layer. The effect of electric field on recombination region is obvious from the variations of the spectra. The I-V curve shows bulk-control for hole-transporting materials acting as electron-transporting layer at high field in bilayer devices, while it shows contact-control for electron-transporting materials.
