brought together people with different expertise,” Zia notes. “Our group’s expertise at Brown is in developing new forms of spectroscopy and studying the electronic origin of light emission. The Kymissis group at Columbia has a great deal of expertise in organic semiconductors, and the Shan group at Case Western has a great deal of expertise in layered nanomaterials. Jon Schuller, the study’s first author, did a great job in bringing all this expertise together. Jon was a visiting scientist here at Brown, a postdoctoral fellow in the Energy Frontier Research Centre at Columbia, and is now a professor at UCSB.”
This work is further detailed in the paper, “ Orientation of luminescent excitons in layered nanomaterials,” by Jon A. Schuller et al in Nature Nanotechnology (2013), published online on 3rd March 2013. DOI: 10.1038/nnano.2013.20

Cree’s $10 LED bulb is a
gamechanger The firm’s III-nitride based LED bulb is shaped like a traditional light bulb but works more efficiently and lasts 25 times longer. It provides a compact optically balanced light source within a real glass bulb to deliver warm light to consumers
Cree is launching a revolutionary series of LED bulbs at a retail price point that gives consumers a reason to switch to LED lighting.
The long-lasting Cree LED bulbs shine as brightly as comparable incandescents while saving 84 percent of the energy compared to traditional bulbs. The Cree LED bulbs are backed by a 10-year limited warranty and available exclusively at The Home Depot.
a no-compromise lighting experience at a compelling price,” says Chuck Swoboda, Cree chairman and CEO. “Over the last couple of years we recognised that the consumer is instrumental in the adoption of LED lighting, but we needed to give them a reason to switch.”
“We believe this breakthrough LED bulb will, for the first time, give consumers a reason to upgrade the billions of energy- wasting light bulbs. We could not think of a better way to get this bulb into consumers’ hands than through The Home Depot, a visionary partner who embraces innovation,” continues Swomboda.
“As the leading retailer of energy-efficient LED lighting products, our customers look to us to provide them with the most advanced and most cost-effective lighting technologies available,” comments Jeff Epstein, merchandising vice president, The Home Depot. “We diligently work with our manufacturing partners to offer consumers the most innovative alternatives that also help save money and energy. We are pleased to expand our relationship with Cree. It has enabled us to be the first in the market to offer a technologically advanced and affordable LED light bulb in the market today.”
The innovative bulb is illuminated by Cree LED Filament Tower Technology and provides a compact optically balanced light source within a real glass bulb to deliver consumers the warm light they love and want. Boasting a shape that looks like a traditional light bulb, Cree LED bulbs can be placed in most lighting fixtures in the home. The new Cree LED bulb is designed to last 25,000 hours or 25 times longer than typical incandescent light bulbs - reducing the need to replace bulbs for years to come.
With a retail price of $9.97 for the warm white 40 watt (W) replacement, $12.97 for the 60W warm white replacement and $13.97 for the 60W day light, the Cree LED bulbs save 84 percent of the energy compared to traditional incandescents.
Cree LED bulbs can pay for themselves quickly and then pay consumers year after year. By replacing the incandescent bulbs with Cree LED bulbs in a home’s five most frequently used light fixtures, consumers can save $61 per year on electric bills. This is based on Cree LED bulb 60W replacements at 9.5 W, $0.11 per kilowatt-hour, 25,000 hour lifetime and average usage of 6 hours per day.
Cree LED bulbs are the ideal replacement for energy-wasting 60W and 40W incandescents and compromise-laden CFL lighting. The new LED bulbs turn on instantly and are free of the mercury that is found in CFL bulbs. Unlike many low-priced LED bulbs, Cree LED bulbs are easily dimmable with most standard incandescent dimmers.
The Cree LED light bulb (60W incandescent replacement) delivers 800 lumens and consumes only 9.5W and is available in warm white (2700K) and day light (5000K) colour temperatures. The Cree LED light bulb (40W incandescent replacement) delivers 450 lumens and consumes only 6W and is available in 2700K colour temperature.
