Abstract

The performance of organic light-emitting devices (OLEDs) based on a small molecular fluorene material, 6,6'-(9H-fluoren-9,9-diyl)bis(2,3-bis(9,9-dihexyl-9H-fluoren-2-yl)quinoxaline) (BFLBBFLYQ), was investigated. Double-layer devices with a structure of indium tin oxide (ITO)/BFLBBFLYQ/2,9-dimethyl-4,7-diphenyl-l, 10-phenanthroline (BCP)/Mg:Ag were fabricated. To improve the performance of the OLEDs, N,N'-biphenyl-N,N'-bis-(3-methylphenyl)-1, 1'-biphenyl-4,4'-diamine (TPD) was introduced, and triple-layer OLEDs with a configuration of ITO/TPD/BFLBBFLYQ/BCP/Mg:Ag were fabricated. By analyzing the electric and luminescent properties of the devices with two different structures, it was found that the performance of triple-layer devices was higher than that of double-layer device. The electroluminescent (EL) spectra of the devices were also studied, which showed that the EL spectra red-shifted as the vacuum deposition temperature increased.
