| 摘 要： | 研究了一种利用无荧光稀土配合物与同一受体材料形成的界面激基复合物的发射来大致估算其最低未占据轨道(LUMO)能级简单方法.镥、钆、钪三种稀土配合物与星形爆炸物形成的激基复合物发射峰位分别在590,607和656 nm,与此相对应LUMO能级计算结果大致为3.0,3.06,3.21 eV.

| Abstract: | A simple method for approximately accounting the lowest unoccupied molecular orbital (LUMO) level of RE-complexes from their exciplex emissions with low ionization potential hole transfer material, 4,4′,4″-tris3-methyl-pheny(phenyl)amino]triphenylamine (m-MTDATA) was investigated. The EL emission peaks located at 590,607,and 656 nm, and the LUMO levels of the RE-complexes approximately were calculated to be about 3.0, 3.06 and 3.21 eV for the Lu-, Gd- and Sc-complexes, respectively. |
