Quickly designing a white LED

The advent of the white light emitting diode (LED), which consists of a blue LED with a phosphor layer, greatly reduces the energy consumption for lighting. Despite the fast-growing market, white LEDs are still being designed ...

Physicists score double hit in LED research

In two breakthroughs in the realm of photonics, City College of New York graduate researchers are reporting the successful demonstration of an LED (light-emitting diode) based on half-light half-matter quasiparticles in atomically ...

Researchers demonstrate low voltage LEDs

When atomically thin semiconductors are combined together in a Lego style, they emit light at a lower voltage potentially leading to low energy consumption devices.

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 ...
