  • Narrowband nanocomposite photodetector
    Patent number: 10651409
    Abstract: A photodetector includes an anode that is transparent or partially transparent to light, a cathode and an active layer disposed between the anode and the cathode. The active layer includes a nanocomposite material that has a polymer blended with nanoparticles or organic electron trapping particles. The photodetector has a low dark current when not illuminated by light and has a high conductivity when illuminated by light, in which the light passes the anode and is absorbed by the active layer. The active layer has a thickness selected such that the photodetector has a narrowband spectral response.
    Type: Grant
    Filed: November 29, 2016
    Date of Patent: May 12, 2020
    Assignee: NUtech Ventures
    Inventors: Jinsong Huang, Fawen Guo, Liang Shen
