  • UV LED with tunnel-injection layer
    Patent number: 9705030
    Abstract: An ultraviolet (UV) light emitting structure, a UV light emitting device, and a method of making a UV light emitting structure or device, wherein the UV light emitting structure or device has an AlN or AlGaN injection layer with high aluminum content between the light emitting active region and the p-doped layers and wherein the injection layer has a thickness such that holes can tunnel from the p-side of the semiconductor-based ultraviolet light emitting diode structure through the injection layer in the active zone and also reducing leakage electrons out of the active zone.
    Type: Grant
    Filed: April 18, 2013
    Date of Patent: July 11, 2017
    Assignees: Technische Universität Berlin, Forschungsverbund e.V.
    Inventors: Michael Kneissl, Tim Kolbe
  • Flow cytometer disinfection module
    Patent number: 9498550
    Abstract: A flow cytometer disinfection module is useful for disinfecting a sheath fluid in a flow cytometer. The module includes a flow cell and at least one UV-C and/or UV-B light source. The UV-C and/or UV-B light source is disposed about the cell and irradiates a sheath fluid passing through the cell.
