Green light for a new generation of dynamic materials

Developing synthetic materials that are as dynamic as those found in nature, with reversibly changing properties and which could be used in manufacturing, recycling and other applications, is a strong focus for scientists.

Highly economical LED street lights tested in practice

Researchers of Karlsruhe Institute of Technology (KIT) have developed a novel, even more economical LED street light. They replaced conventional high-performance diodes by a special array of weaker LEDs and, thus, succeeded ...

Record efficiency for perovskite-based light-emitting diodes

Efficient near-infrared (NIR) light-emitting diodes of perovskite have been produced in a laboratory at Linköping University. The external quantum efficiency is 21.6 percent, which is a record. The results have been published ...

NIST researchers boost intensity of nanowire LEDs

Nanowire gurus at the National Institute of Standards and Technology (NIST) have made ultraviolet light-emitting diodes (LEDs) that, thanks to a special type of shell, produce five times higher light intensity than do comparable ...

Engineered light could improve health, food, suggests researcher

People who believe light-emitting diodes, or LEDS, are just an efficient upgrade to the ordinary electric light bulb are stuck in their thinking, suggest Sandia National Laboratories researcher Jeff Tsao and colleagues from ...

A new generation of organic light-emitting diodes

Another major success for the University of Bayreuth: over the next four years, the university will be coordinating an intercontinental research network that has 3.9 million euros in funding. Taking an interdisciplinary approach, ...
