Scientists break light modulation speed record -- twice
Researchers have constructed a light-emitting transistor that has set a new record with a signal-processing modulation speed of 4.3 gigahertz, breaking the previous record of 1.7 gigahertz held by a light-emitting diode. view more (2009-06-16)
RC-LEDs - Super-fast light sources suitable for data transfer
Resonance-cavity light-emitting diodes (RC-LEDs) are a new type of light source which produces very intense light from quantum wells located in a microcavity. As light sources, RC-LEDs are classified as something between laser diodes and conventional light-emitting diodes (LEDs). The advantages of RC-LEDs compared with conventional LEDs include a... view more... (2000-02-25)
Growing glowing nanowires to light up the nanoworld
The nano world is getting brighter. Nanowires made of semiconductor materials are being used to make prototype lasers and light-emitting diodes with emission apertures roughly 100 nm in diameter-about 50 times narrower than conventional counterparts. view more (2006-05-26)
New materials for high efficiency organic solid state lighting
A new organic molecule developed by Pacific Northwest National Laboratory scientists may significantly improve the efficiency of organic solid state lighting. Direct conversion of electricity to light in "solid state" thin films of organic molecules occurs in organic light emitting devices which can be far more efficient than... view more... (2006-03-30)
Optical wireless and broadband over power lines: High speed, secure Wi-Fi alternative
Penn State engineers have shown that a white-LED system for lighting and high data-rate indoor wireless communications, coupled with broadband over either medium- or low-voltage power line grids (BPL), can offer transmission capacities that exceed DSL or cable and are more secure than RF. view more (2006-01-12)
Plastic electronics for light diodes and prostheses
Is it possible to make components out of organic polymers (plastics) whose structure is such that severed nerves can grow right into them and connect with electrodes in a prosthetic hand, for example? This is one of the research fields for Tobias Nyberg at the Section for Biomolecular and Organic Electronics at Linköping University, Sweden.... view more... (2002-04-29)
NIST method may help optimize light-emitting semiconductors
Physicists at JILA have demonstrated an ultrafast laser technique for "seeing" once-hidden electronic behavior in semiconductors, which eventually could be useful in more predictable design of optoelectronic devices, including semiconductor lasers and white light-emitting diodes. view more (2006-02-17)
Scientists demonstrate method for integrating nanowire devices directly onto silicon
Applied scientists at Harvard University in collaboration with researchers from the German universities of Jena, Gottingen, and Bremen, have developed a new technique for fabricating nanowire photonic and electronic integrated circuits that may one day be suitable for high-volume commercial production. view more (2008-05-09)
Baby boomers' boon? LED light and green tea cream to smooth facial wrinkles
Scientists in Germany are reporting a major improvement in their potential new treatment for facial wrinkles that could emerge as an alternative to Botox and cosmetic surgery. view more (2009-09-10)
Novel nano-etched cavity makes leds 7 times brighter
Researchers at the National Institute of Standards and Technology (NIST) have made semiconductor light-emitting diodes (LEDs) more than seven times brighter by etching nanoscale grooves in a surrounding cavity to guide scattered light in one direction. view more (2006-07-24)
A bright future for plastics -- robot 'skin,' flexible laptops and electric posters
With market analysts predicting a ten fold increase in the value of the organic light emitting display industry, from £1.5 billion to £15.5 billion, by 2014, it is no wonder that scientists and governments alike are keen to advance research into "plastic electronics". view more (2008-07-01)
Displays for the pants pocket
Much to the disappointment of many users of computer and portable electronic information device, flexible screens still cannot be found in retail stores. The reasons are mainly of technical and chemical nature, as Dr. Armin Wedel from the Fraunhofer Institute for Applied Polymer Research IAP explains: "Many developers of displays which you... view more...
