Tiny LED Is Way More Efficient and Can Be A Laser Too
September 2, 2020 | Leave a Comment
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 […]

An All New Light Emitting Diode
April 25, 2019 | Leave a Comment
Scientists at TU Wien (Vienna) have now succeeded in using exotic bound states of particles to create a novel kind of light-emitting diode. In ultra thin materials, exotic bound states of particles can be created which are then converted into light. When particles bond in free space, they normally create atoms or molecules. However, much […]

Got CFL Bulbs? Might Wait For Better LEDs
November 22, 2017 | 9 Comments
University of Michigan researchers recommend replacing all incandescent and halogen light bulbs in your home now with compact fluorescent lamps (CFLs) or LEDs. With LED light bulbs are getting cheaper and more energy efficient every year, does it make sense to replace less-efficient bulbs with the latest light-emitting diodes now, or should you wait for […]

LED Build Process Successfully Uses Perovskites
January 24, 2017 | Leave a Comment
Princeton University researchers have built another path forward for LED technologies. By refining the manufacturing of light sources made with crystalline substances known as perovskites, a more efficient and potentially lower-cost alternative to materials used in today’s LEDs can be made. Just as the complexity and bulkiness of CFLs distorted the engineering and lighting market, […]

University of Toronto engineers have combined two promising solar cell materials together for the first time, creating a new platform for LED technology. The team has designed a way to embed the strongly luminescent nanoparticles called colloidal quantum dots into perovskite. Researchers in The Edward S. Rogers Sr. Department of Electrical & Computer Engineering invented […]
