研究了稀土(RE)配合物(RE=Sc、Gd或Lu)(RE-配合物中的RE离子为三价离子)的有机二极管,在电驱动和紫外光照射下分别表现出电致发光(EL)和光伏(PV)特性。作为EL二极管时,m-MT-DATA(4,4′,4-″tris[3-methyl-pheny(phenyl)-amino]triphenyl-amine)和稀土配合物分别用作空穴和电子传输材料,EL发射仅仅来自m-MTDATA和稀土配合物层间界面激基复合物,当配合物的中心金属分别为Sc、Gd或Lu时,EL发射峰分别为656、607~590nm。作为PV二极管时,m-MTDATA和稀土配合物分别作为电子给体(D)和受体(A),它们的开路电压(Voc)分别为1.17、1.65和1.92V。还讨论了EL和PV特性与配合物中中心稀土离子的核电荷数关系。
The organic diodes of rare earth (RE) complexes (RE = Sc, Gd or Lu) (RE ions in trivalent doping ions in RE complexes) were studied and showed electroluminescence EL) and photovoltaic (PV) characteristics. As an EL diode, m-MT-DATA (4,4 ’, 4 "tris [3-methyl-pheny (phenyl) -amino] triphenyl-amine and rare earth complexes are used as hole and electron transport materials, respectively, The EL emission only comes from the exciplex of the interface between m-MTDATA and the rare-earth complex, and the EL emission peaks are 656 and 607-590 nm, respectively, when the central metal of the complex is Sc, Gd or Lu, respectively. As a PV diode, The open circuit voltage (Voc) of m-MTDATA and the rare earth complex as the electron donor (D) and the acceptor (A), respectively, were 1.17, 1.65 and 1.92 V. It was also discussed that the EL and PV properties were similar to those of the center Rare earth ion nuclear charge number relationship.
