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 ...

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, ...

Directivity to improve optical devices

A team of researchers from the Dutch institute AMOLF, Western University (Canada), and the University of Texas (United States of America) recently demonstrated the use of algorithmic design to create a new type of nanophotonic ...

Perovskites – materials of the future in optical communication

Researchers at the universities of Linköping and Shenzhen have shown how an inorganic perovskite can be made into a cheap and efficient photodetector that transfers both text and music. "It's a promising material for future ...

Samsung's foldable phone could soon be a reality

We rarely see a truly remarkable new technology more than once a decade. After years of undelivered promises, such a technology looks finally set to enter the market: the flexible computer screen.

Creating displays with richer colours

National University of Singapore researchers have developed a colour-enhancement film that could bring richer and more natural colours to next-generation flat-panel electronic displays.
