What Is A Light-Emitting Diode? A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. LEDs function by converting electrical current into ...

OLEDs are also commonly referred to as organic LEDs and organic electroluminescent diodes. They operate due to the phenomenon of electroluminescence. A thin organic film is sandwiched between two ...

An upconversion organic light-emitting diode (OLED) based on a typical blue-fluorescence emitter achieves emission at an ultralow turn-on voltage of 1.47 V. The technology circumvents the traditional ...

Tokyo, Japan – Scientists from Tokyo Metropolitan University have developed a new electrode material for deep-ultraviolet (DUV) light-emitting diode applications. They used a cutting-edge deposition ...

To be more energy efficient, many people have replaced their incandescent lights with light-emitting diode (LED) bulbs. However, those currently on the market emit a lot of blue light, which has been ...

A deep blue organic light-emitting diode (OLED) developed by researchers at Science Tokyo operates on just a single 1.5 V, overcoming the high-voltage and color-purity problems that have long limited ...

A research team has successfully synthesized a new class of helical quinolizinium salts exhibiting exceptionally strong fluorescence in the orange-to-red light region (606–682 nm). Smart glasses that ...

This illustration depicts the QAO family dopant integrated into the organic light-emitting diode structure. By designing a molecule with a lower HOMO level than that of the host material, the ...

Just a general observation: when your project’s BOM includes ytterbium metal, chances are pretty good that it’s something interesting. We’d say that making your own OLED displays at home definitely ...
