A Thermally Stable Organic Light-Emitting Diode

1995
The design of organic electroluminescence (EL) devices meets several barriers, thermal stability and injection ability of charge carriers from the electrodes being important examples. In spite of considerable efforts to surmount them,1 they still create serious problems and require more experimental data and profounded knowledge on the device operation.

Photochemistry of Organic Light-Emitting Diodes

AIP Conference Proceedings, 2007
The optical properties and excited‐state geometries of some organic light‐emitting diodes have been investigated by the SAC‐CI method. The absorption and emission spectra have been predicted in high accuracy and the chain‐length dependence of transition energies has been precisely reproduced.

Models of organic light-emitting diodes

Synthetic Metals, 1997
Abstract Based upon the recognition that bimolecular charge recombination in random organic systems is in accord with the Langevin formalism, a simple model has been developed to treat the recombination of charge carriers in light-emitting diodes (LEDs).

Organic Light-emitting Diodes

2014
Organic light-emitting diodes (OLEDs) are another type of LED and have a more recent history, with origins in the 1950s. The demand for cheap, compact and low-power consuming light sources for displays in the increasing range of consumer products and electronic devices helps to drive research and development in light-emitting diodes, quantum dots and ...

Light Emitting Efficiencies in Organic Light Emitting Diodes (OLEDs)

2001
The interface between the organic layer and metallic anode of an OLED is crucial to the stability and the performance of the device. The α-septithiophene (α-7T) has been used as the buffer layer at the interface between the ITO electrode and the hole transport layer (HTL).

Light Emitting Diode and Organic Laser

2011
The development of semiconductor lasers is accompanied by the development of light emitting diodes (LEDs). An LED, based on spontaneous electron-hole recombination, does not require a cavity and can therefore have a simpler design than a laser. We discuss properties of diodes and mention various areas of applications.
