LOS ANGELES, May 18, 2007 -- Single-layer, inexpensive plastic LEDs are being developed that could make the next generation of flat-panel TVs brighter, clearer and less expensive. The record-breaking research will be presented at the Society for Information Display (SID) 2007 conference in Long Beach, Calif., from May 20-25. Most people probably don’t think much about the inner workings of LEDs, or light-emitting diodes, which illuminate today’s plasma TV screens and cell phones, but making these LEDs more efficient, cheaper and higher quality is the obsession of University of California, Los Angeles materials science...Read full article

    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...

    polymer
    Polymers are large molecules composed of repeating structural units called monomers. These monomers are chemically bonded together to form long chains or networks, creating a macromolecular structure. The process of linking monomers together is known as polymerization. Polymers can be classified into several categories based on their structure, properties, and mode of synthesis. Some common types of polymers include: Synthetic polymers: These are human-made polymers produced through...
