Organic Light-Emitting Diodes

2017
The 2014 Nobel Prize in Physics was awarded “for the invention of efficient blue light-emitting diodes (LEDs) which has enabled bright and energy-saving white light sources” [1, 2, 3], setting a clear target to mankind: energy-efficient and environmental-friendly light sources [4]. The first organic LED (OLED) was reported in 1987 by a team at Kodak [5]

Tandem Organic Light‐Emitting Diodes

Advanced Materials, 2016
A tandem organic light‐emitting diode (OLED) is an organic optoelectronic device that has two or more electroluminescence (EL) units connected electrically in series with unique intermediate connectors within the device. Researchers have studied this new OLED architecture with growing interest and have found that the current efficiency of a tandem OLED

Nanoscale Organic Light-Emitting Diodes

Nano Letters, 2005
This study reports the fabrication and characterization of nanoscale organic light-emitting diodes (nano-OLEDs) based on poly[2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylene vinylene] (MEH-PPV). The nano-OLEDs were fabricated by spin casting MEH-PPV into cylindrical nanoholes lithographically patterned into silicon nitride.

Photoprogrammable Organic Light‐Emitting Diodes

Angewandte Chemie, 2009
AbstractLicht im Speicher: Der Einbau eines vernetzbaren photochromen Dithienylperfluorcyclopentens (DTE) in organische Leuchtdioden (OLEDs) ermöglicht die Individualisierung der Emissionsfläche, z. B. für die Anwendung in Anzeigeelementen. Das Arbeitsprinzip beruht auf dem Schalten der Injektionsbarriere für Löcher (positive Ladungsträger). Sehr große
