Goodbye, fluorescent light bulbs: New lighting technology won't flicker, shatter or burn out
Say goodbye to that annoying buzz created by overhead fluorescent light bulbs in your office. Scientists at Wake Forest University have developed a flicker-free, shatterproof alternative for large-scale lighting.
White LEDs with super-high luminous efficacy could satisfy all general lighting needs
Light from a water bottle could brighten millions of poor homes (w/ video)
Wagon-wheel pasta shape for better LED: 'Rotelle' molecules depolarize light more efficiently than 'spaghetti'
One problem in developing more efficient organic LED light bulbs and displays for TVs and phones is that much of the light is polarized in one direction and thus trapped within the light-emitting diode, or ...
Toward a truly white organic LED: Physicists develop polymer with tunable colors
By inserting platinum atoms into an organic semiconductor, University of Utah physicists were able to "tune" the plastic-like polymer to emit light of different colors – a step toward more efficient, less ...
Cause of LED efficiency droop finally revealed: Auger recombination responsible
(Phys.org)—Researchers at University of California, Santa Barbara, in collaboration with colleagues at the École Polytechnique in France, have conclusively identified Auger recombination as the mechanism ...
Pyramid scheme for brighter organic LEDs
The most common kind of light bulb in the United States—the incandescent—is only about 5 percent efficient. The phosphorescent organic light-emitting diode, on the other hand, makes light out of 100 percent ...
Fiber laser points to woven 3-D displays
Most light emitters, from candles to light bulbs to computer screens, look the same from any angle. But in a paper published this week on the Nature Photonics website, MIT researchers report the development of a n ...
Quantum dots brighten the future of lighting
(Phys.org) -- With the age of the incandescent light bulb fading rapidly, the holy grail of the lighting industry is to develop a highly efficient form of solid-state lighting that produces high quality white ...
OLED Tunes its Colors for Sunlight-Style Illumination
Proton-based transistor could let machines communicate with living things
Human devices, from light bulbs to iPods, send information using electrons. Human bodies and all other living things, on the other hand, send signals and perform work using ions or protons.
Altering organic molecules' interaction with light
Enhancing and manipulating the light emission of organic molecules is at heart of many important technological and scientific advances, including in the fields of organic light emitting devices, bio-imaging, ...
US energy use chart shows we waste more than half of our energy
Antenna-on-a-chip rips the light fantastic
(Phys.org)—A device that looks like a tiny washboard may clean the clocks of current commercial products used to manipulate infrared light.
