That palm tree magnet commemorating your last vacation is programmed for a simple function - to stick to your refrigerator. Similarly, semiconductors are programmed to convey bits of information small and large, processi...
A new process for creating ultrathin, ultrasmall inorganic light-emitting diodes (LEDs) and assembling them into large arrays offers new classes of lighting and display systems with interesting properties, such as see-through construction and mechanical flexibility, that would be impossible to achieve with existing technologies.
Veeco Instruments Inc. (Nasdaq: VECO) announced today that Philips Lumileds Lighting Company, the world's leading manufacturer of high-power light emitting diodes (LEDs) and a solid-state lighting industry pioneer, h...
The University of Georgia Research Foundation, Inc. (UGARF) and the University of Puerto Rico have granted an international, non-exclusive license for a portfolio of glow-in-the-dark pigments that can be designed to emit light in any color of the visible spectrum for nearly a day. Performance Indicator, LLC, of Lowell, Mass., acquired the license.
Researchers have modified nanoparticles known as "Cornell dots" to make the world's tiniest laser -- so small it could be incorporated into microchips to serve as a light source for photonic circuits. The device may also have applications for sensors, solar collectors and in biomedicine.
And with an average service life of 25,000 hours, it outlasts an incandescent lamp by a dazzling factor of 25. All told, every lamp will save almost EUR 200 in electricity, as well as more than 400 kg of CO2 emissions.
t already achieves an optical output of 50 mW and emits light in true green with a wavelength of 515 nm. Compared with semiconductor lasers based on current technology that operate with frequency doubling, direct emitting green lasers are more compact, offer greater temperature stability, are easier to control and have higher modulation capability.
A total of six lamps with the latest LED technology from OSRAM demonstrate street lighting of the future in Fürth near Nuremberg, Germany. The city's traffic and energy supply company infra fürth GmbH, lumi...
With its Powerball HCI 100W lamps Munich lighting manufacturer OSRAM now provides 100W systems for halogen metal halide lamps with ceramic burners for the first time.
A team of Brookhaven and Argonne National Laboratory researchers has demonstrated a reliable path for sculpting an intricate x-ray focusing lens out of diamond. Their technique, which was published in the January 2009 edition of the Journal of Synchrotron Radiation, could prove extremely valuable in the study of nanomaterials at future synchrotron light sources.
