Engineers in Switzerland have built light-emitting diodes so small that hundreds could line up across the width of a single ...

A new one-step process miniaturises OLEDs to smaller than their emitted wavelength, enabling precise control of light ...

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 ...

This video explains how LEDs (Light Emitting Diodes) function and why they are widely used in modern electronics. LEDs produce light by emitting energy when electrons recombine with holes in a ...

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 ...

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 ...

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 ...
