Nanoscale LEDs Emit UV Light

Facebook X LinkedIn Email
GAITHERSBURG, Md., May 25, 2007 -- Nanowires have been used to create tiny, highly efficient ultraviolet LEDs that could help build the next generation of biosensors and optical communications devices. Researchers at the National Institute of Standards and Technology (NIST) in Gaithersburg developed the assembly technique, which they said can be readily adapted for commercial production, in collaboration with scientists from the University of Maryland in College Park and Howard University in Washington. While the creation of nanoscale LEDs is not new, what is notable is that the NIST LEDs emit ultraviolet (UV) light....Read full article

    Glossary
    light
    Electromagnetic radiation detectable by the eye, ranging in wavelength from about 400 to 750 nm. In photonic applications light can be considered to cover the nonvisible portion of the spectrum which includes the ultraviolet and the infrared.
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    optical communications
    The transmission and reception of information by optical devices and sensors.
    photolithography
    Photolithography is a key process in the manufacturing of semiconductor devices, integrated circuits, and microelectromechanical systems (MEMS). It is a photomechanical process used to transfer geometric patterns from a photomask or reticle to a photosensitive chemical photoresist on a substrate, typically a silicon wafer. The basic steps of photolithography include: Cleaning the substrate: The substrate, often a silicon wafer, is cleaned to remove any contaminants from its surface. ...
    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...
    sensor
    1. A generic term for detector. 2. A complete optical/mechanical/electronic system that contains some form of radiation detector.
