Exciplex Emission

A white organic light-emitting diode (WOLED) with an organic quantum well structure of ITO/N,N’-diphenyl-N,N’-bis(3-methylphenyl)-1,1’-biphenyl-4,4’-diamine (TPD) / 4,7-Diphenyl-1,10-phenanthroline (Bphen)/5,6,11,12-tetraphenylnapthacene (Rubrene)/Bphen /LiF/Al was fabricated by vacuum evaporation. The electroluminescence (EL) spectrum of the as-fabricated WOLED covers from 380nm to 700nm of the visible light region with a blue emission from TPD and an interesting wide emission peaked at 525nm, which can be decomposed into three emissions at 480nm, 525nm, and 555nm, respectively. The peaks at 525nm and 555nm are attributed to the excitation emission from the Bphen/Rubrene/Bphen quantum well structure, which are obviously blue-shifted in comparison with the photoluminescence (PL) spectrum of Rubrene. The new peak at 480nm is attributed to the exciplex emission at TPD/Bphen interface since it was also observed in the PL spectra. The white light of the WOLED comes from combined contribution of exciplex emission and organic quantum well structure.

White Oled

A novel deep-blue fluorescent emitter was designed and synthesized. The external quantum efficiency (ηEQE) of the blue-emitting, doped, organic light-emitting diode (OLED) was as high as 4.34%. The device also exhibited an excellent color purity with Commission Internationale de l’Eclairage (CIE) coordinates of x = 0.15 and y = 0.05. In addition, the triplet energy had a value of 2.7 eV, which is rare for an emitter with deep-blue emission, which makes it a preferred choice for high-performance white OLEDs. By optimizing the device architectures, the color of hybrid-white OLEDs could be tunable from warm white to cool white using the aforementioned material as a bifunctional material. That is, the ηEQE of the hybrid warm-white OLED is 20.1% with a CIE x and y of 0.46 and 0.48 and the ηEQE of the hybrid cool-white OLED is 9% with a CIE x and y of 0.34 and 0.33.
