Open Image…Save ImageOpen Image (using #TmpD/ia)… The National Institute of Standards and Technology (NIST) has a new design for light-emitting diodes that achieves a dramatic increase in brightness as well as the ability to create laser light. These characteristics could make it valuable in a range of applications. The device shows an increase in brightness of 100 to 1,000 times […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… A team from Imperial College London and the Indian Institute of Technology (IIT) Guwahati have found a new way to boost the amount of light LEDs produce and increase their lifetime. Its done by adding layer of nanoparticles to LED designs. They report their innovation in the journal Light Science & Applications. Making light-emitting […]

Los Alamos National Laboratory researchers have developed new quantum dot solar cells that match the efficiency of existing quantum-dot based devices, but without lead or other toxic elements relied on by most solar cells of this type. Victor Klimov, a physicist specializing in semiconductor nanocrystals at Los Alamos and lead author of the report featured […]

Paul Scherrer Institute researchers have gained insights into a promising material for organic light-emitting diodes (OLEDs). The substance enables high light yields and would be inexpensive to produce on a large scale, which means such diodes are practically made for use in large-area room lighting. Researchers have been searching for such materials for a long […]

Linköping University researchers have developed a perovskite light-emitting diode (LED) with both high efficiency and long operational stability. Working with colleagues in Great Britain, China and the Czech Republic developing the perovskite light-emitting diode (LED) the team’s results have been published in Nature Communications. Professor Feng Gao, and head of research at the Division of […]
