This chapter presents an introduction toorganic light-emitting diodes(OLEDs), which are solid-statelight sourcesmade oforganic semiconductor(OSC) materials. Variousfunctional materialshelp to facilitate the conversion of injected charges into emitted photons at the maximum possible efficiency, and further...
A laser diode is a semiconductor laser device that is very similar, in both form and operation, to a light-emitting diode (LED). The term laser originated as an acronym: Light Amplification by Stimulated Emission of Radiation. Hence, a laser is a device that emits light through a process ...
An Infrared LED is a specialized light-emitting diode that emits light in the infrared spectrum, invisible to the human eye but essential for various electronic devices like remote controls and security cameras. It's a silent, unseen beacon that powers our tech-driven world. Intrigued by how th...
An undoped charge-generation unit (CGU) with the structure of lithium fluoride (LiF)/aluminum/molybdenum trioxide (MoO3) was demonstrated in tandem organic light-emitting diodes (OLEDs). Tandem OLEDs with two identical emissive units consisting of 4,4-bis-(1-naphthyl-N-phenylamino)-biphenyl (...
Light-emitting diodes as an alternative supplemental lighting source for greenhouse tomato propagation and production. Intensive year-round local production of greenhouse-grown tomatoes ( Solanum lycopersicum L.) requires the use of supplemental lighting (SL) to complement ... Gomez,Vargas,Celina. - Pu...
The potential of organic semiconductor-based devices for light generation is demonstrated by the commercialization of display technologies based on organic light-emitting diodes (OLEDs). Nonetheless, exciton quenching and photon loss processes still limit OLED efficiency and brightness. Organic light-emittin...
We have fabricated highly efficient organic light-emitting diodes (LEDS) usingin situthermally polymerized hole transporting materials containing triphenylamine/tetraphenyldiaminobiphenyl as side chains. Double-layer LEDs made with these thermally polymerized polymers as the hole transporting layer and tris(8...
(m-MTDATA) are demonstrated.In order to examine the improvement in the conductivity of transport layers,hole-only and electron-only devices are fabricated.The current and power efficiency of organic light-emitting diodes are improved significantly after introducing an n-doping (BPhen:33wt% Liq) ...
