Abstract

The authors report the optical and electroluminescent (EL) properties of white organic light-emitting diodes (OLEDs) which have two emitters with similar structures: 1, 1, 4, 4-tetraphenyl-1, 3-butadiene and 2,9-dimethyl-4,7- diphenyl-1,10-phenanthroline have an emission peak of 400 nm around the near ultraviolet, and tris-(8-hydroxyquinoline) aluminum doped with 4-(dicyanomethylene)-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran has an emission peak of 580 nm producing a yellow color. The EL spectra of the white OLED have shown a broadening through visual range from 400 to 780 nm. This spectral broadening is related to an exciplex emission at the organic solid interface.
