- Abstract
- A new light-emissive material, bis-2-(4-(diphenylphosphino)phenyl)benzo[d] oxazole (DPB), has been synthesized and characterized by FT-NMR, FT-IR, UV-Vis and elemental analysis. DPB has the band gap of 4.3 eV between HOMO and LUMO levels. The photoluminescence (PL) of DPB was measured at 410 nm from the chloroform solution. The electroluminescent (EL) devices with structures of ITO/NPB/DPB/LiF/Al and ITO/NPB/DPB/Alq(3)/LiF/Al were constructed and showed maximum emission at 540 nm. The device using DPB as emitting material showed the luminance of 1000 cd/m(2) at 11 V. The CIE chromaticity of the device showed near the region of white color emission.
