White Organic Light‐Emitting Diodes
Advanced Materials, 2010AbstractWhite organic light‐emitting diodes (WOLEDs) offer a range of attractive characteristics and are in several regards conceptually different from most currently used light sources. From an application perspective, their advantages include a high power efficiency that rivals the performance of fluorescent lamps and inorganic LEDs and the potential

Organic light emitting diodes with a complex multilayer structure have been successfully fabricated for bright light emission in the entire visible spectral region. The CIE coordinates of the blue, green, and red emitting electroluminescent devices are plotted in the chromaticity diagram. Double heterostructure organic LEDs with separate hole injection

Hybrid Organic–Inorganic Light‐Emitting Diodes
Advanced Materials, 2011AbstractThe demonstration of colour tunability and high efficiency has brought organic light‐emitting diodes (OLEDs) into the displays and lighting market. However, high production costs due to expensive deposition techniques and the use of reactive materials still limit their market entry, highlighting the need for novel concepts.

Biologically Inspired Organic Light-Emitting Diodes
Nano Letters, 2016Many animal species employ highly conspicuous traits as courtship signals for successful mating. Fireflies utilize their bioluminescent light as visual courtship signals. In addition to efficient bioluminescent light emission, the structural components of the firefly lantern also contribute to the enhancement of conspicuous optical signaling. Recently,

Multilayer organic light-emitting diodes
Solid State Communications, 1996Abstract Organic electroluminescent devices are light-emitting diodes (LEDs) in which the active components are entirely organic in nature. In this work, heterostructural LEDs composed of conjugated conducting polymer poly(p-phenylene vinylene) (PPV) layer, fluorescent molecular compound tris(8-hydroxy) quinoline aluminum (Alq 3 ) layer, and 2-(4 ...
