Abstract: It is well known that inclined sidewall scattering structures can improve the light extraction efficiency (LEE) of micro deep ultraviolet (DUV) light-emitting diodes (LEDs). However, ...

Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

African forests are now emitting more carbon dioxide than they absorb, a fundamental shift that will make it more difficult for the world to cut its net emissions to zero. Forests and shrubby ...

This ETH Zurich logo consists of 2,800 nano light-emitting diodes and, at a height of 20 micrometers, matches the size of a human cell.Amanda Paganini / ETH Zurich Swiss researchers have built organic ...

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 ...

The rear lights on the VW Touareg put on a show! This video captures the dynamic light signature in action—bright, animated, and super sleek. It’s like a mini fireworks display every time you unlock ...

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 ...

This weekend, more than 1,900 U.S. theaters will screen the mostly hand-drawn 2D animated feature Light of the World, which adapts the Biblical story of Jesus through the eyes of the youngest disciple ...

Interstellar object 3I/ATLAS — which is zooming through our inner solar system — appears to be emitting its own light, according to Harvard astrophysicist Avi Loeb. The observation by Loeb, if ...

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 ...

In a first for the field, researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have reported a photopumped lasing from a buried dielectric ...
