Quantum Dots May Enable New Radiation Detectors

Facebook X LinkedIn Email
Daniel S. Burgess

The work of a pair of scientists at Lawrence Livermore National Laboratory in Livermore, Calif., indicates that quantum dots may serve as suitable scintillator materials for the development of high-resolution room-temperature gamma-ray detectors. Such detectors have potential applications in medical imaging, environmental monitoring, and security and defense. Tzu-Fang Wang, who is collaborating on the project with Sonia E. Létant, said that contemporary approaches to gamma-ray detection carry several drawbacks. Most still employ a photomultiplier tube and single-crystal thallium-activated...Read full article

    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.
