چکیده

We present the results of an optical study in which we evaluate the effect of anisotropic electron transport layers (ETL) and anisotropic hole transport layers (HTL) on the outcoupling efficiency of bottom emitting organic light emitting diodes (OLEDs). We demonstrate that optical anisotropy can have a profound influence on the outcoupling efficiency and introduce a number of design rules which ensure that light extraction is enhanced by anisotropic layers.

Exceptionally efficient organic light emitting devices using high refractive index substrates.

Organic light emitting devices (OLEDs) are now used in commercial cell phones and flat screen displays, but may become even more successful in lighting applications, in which large area, high efficiency, long lifetime and low cost are essential. Due to the relatively high refractive index of the organic layers, conventional planar bottom emitting OLEDs have a low outcoupling efficiency. Various...

Enhanced Outcoupling in Organic Light-Emitting Diodes via a High- Index Contrast Scattering Layer

Despite high internal quantum efficiencies, planar organic light-emitting diodes (OLEDs) typically suffer from limited outcoupling efficiencies. To improve this outcoupling efficiency, we have developed a new thin (∼2 μm) light scattering layer that employs air voids (low-index scattering centers) embedded in a high-index polyimide matrix to effectively frustrate the substrate-trapped light, in...

Coherent mode coupling in highly efficient top-emitting OLEDs on periodically corrugated substrates.

Bragg scattering at one-dimensional corrugated substrates allows to improve the light outcoupling from top-emitting organic light-emitting diodes (OLEDs). The OLEDs rely on a highly efficient phosphorescent pin stack and contain metal electrodes that introduce pronounced microcavity effects. A corrugated photoresist layer underneath the bottom electrode introduces light scattering. Compared to ...

Efficient and stable single-doped white OLEDs using a palladium-based phosphorescent excimer† †Electronic supplementary information (ESI) available. See DOI: 10.1039/c7sc02512b

A tetradentate Pd(ii) complex, Pd3O3, which exhibits highly efficient excimer emission is synthesized and characterized. Pd3O3 can achieve blue emission despite using phenyl-pyridine emissive ligands which have been a mainstay of stable green and red phosphorescent emitter designs, making Pd3O3 a good candidate for stable blue or white OLEDs. Pd3O3 exhibits strong and efficient phosphorescent e...

22.3: High Efficiency Electrophosphorescent Organic Light Emitting Diodes using Semitransparent Ag as Anode

We have significantly improved the emission efficiency in an organic light emitting diode (OLEDs) based on tris(phenyl pyridine)iridium [Ir(ppy)3]. Using a semitransparent Ag with surface modification as anode to replace conventional ITO, excellent light outcoupling and hole injection properties have been realized. The Ag based OLED exhibits a maximum current efficiency of 81 cd/A and power eff...
