Ulsan National Institute of Science and Technology (UNIST) has announced that an international team of researchers has introduced a simple technique to fabricate full-color perovskite LEDs. Perovskite nanoparticles are regarded as next-generation of optical materials that can achieve vivid colors even on very large screens. Due to their high color purity and low cost advantages, […]

Researchers at KoƧ University, Turkey, have demonstrated nanomaterial-based white-light-emitting diodes (LEDs) that exhibit a record luminous efficiency of 105 lumens per watt. Luminous efficiency is a measure of how well a light source uses power to generate light. With further development, the new LEDs could reach efficiencies over 200 lumens per watt, making them a […]

University of California – San Diego researchers used supercomputers and data mining algorithms to develop a new phosphor that can make LEDs cheaper and render colors more accurately. They have developed a simple recipe to make it in the lab and built prototype white LED light bulbs using the new phosphor. The prototypes exhibited better […]

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 […]

University of Turku scientists in Finland have created a synthetic material based on the natural hackmanite mineral which produces broad spectrum white light in lamps. The hackmanite created by the Inorganic Materials Chemistry research group is a low-cost material emitting luminescence closer to sunlight than that of the currently used lanthanides. The hackmanite developed by […]
