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

Miniaturization ranks as the driving force behind the semiconductor industry. The tremendous gains in computer performance since the 1950s are largely due to the fact that ever smaller structures can ...

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

This news release is available in German. Use of copper as a fluorescent material allows for the manufacture of inexpensive and environmentally compatible organic light-emitting diodes (OLEDs).

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 ...

Researchers at ETH Zurich have created some of the smallest light-emitting diodes ever made—so tiny that thousands of them could fit inside a single human cell. These miniature organic LEDs, or ...

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 ...

Organic light-emitting diodes (OLEDs) power the high-end screens of our digital world, from TVs and phones to laptops and ...
