Plasma Coating Offers Cost-effective, Sustainable Alternative to Indium

Facebook X LinkedIn Email
Researchers from the University of Sydney have developed a low-cost, sustainable, and readily available technology that can dim the screens of electronic devices, antireflection automobile mirrors, and smart architectural windows at a fraction of the cost of current technology. Created via a plasma sputtering process, the team’s technology is more accessible than indium, the rare-earth element currently used to provide smart devices with dimming capabilities. Like indium, the team’s plasma-generated structures are optically transparent, electrically conductive, and electrochromic....Read full article

    Glossary
    power
    With respect to a lens, the reciprocal of its focal length. The term power, as applied to a telescope or microscope, often is used as an abbreviation for magnifying power.
    indium
    Metal used in components of the crystalline semiconductor alloys indium gallium arsenide (InGaAs), indium gallium arsenide phosphide (InGaAsP), and the binary semiconductor indium phosphide (InP). The first two are lattice-matched to InP as the light-emitting medium for lasers or light-emitting diodes in the 1.06- to 1.7-µm range, and the last are used as a substrate and cladding layer.
    optoelectronics
    Optoelectronics is a branch of electronics that focuses on the study and application of devices and systems that use light and its interactions with different materials. The term "optoelectronics" is a combination of "optics" and "electronics," reflecting the interdisciplinary nature of this field. Optoelectronic devices convert electrical signals into optical signals or vice versa, making them crucial in various technologies. Some key components and applications of optoelectronics include: ...
    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.
