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

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).

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 ...

Organic Light Emitting Diodes (OLEDs) have gained significant attention since researchers at Eastman Kodak pioneered the development of OLED technology in the 1970s and demonstrated the first ...

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 ...

Colloidal quantum dots (QDs) exhibit exceptional properties of narrow-band emission, tunable luminescent wavelength, high luminous efficiency, and remarkable material stability across the visible and ...

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 ...

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

Researchers from ETH Zurich have manufactured organic light-emitting diodes (OLEDs) on a nanoscale - that's around a hundred times smaller than a ...
