A process developed at ETH Zurich enables the massive miniaturisation of organic light-emitting diodes (OLEDs) in only one single step. The light sources are now smaller than the wavelength of the ...

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 ...

Quantum dot light‐emitting diodes (QD‐LEDs) represent a versatile class of optoelectronic devices that harness the unique properties of semiconductor nanocrystals to produce highly saturated and ...

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 ...

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 ...

Wearable electronics have evolved from basic fitness trackers to sophisticated health-monitoring systems, demanding light-emitting devices that balance visual quality, power efficiency, and mechanical ...

British inventors began experimenting with electric lighting in the 1830s, working on so-called arc lamps, while other scientists around the world focused on developing a functioning incandescent lamp ...

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 ...
