  • ABOS:M-based phosphors and light sources containing these phosphors
    Patent number: 8319417
    Abstract: This invention is related to efficient anorganic phosphors, which are based on an oxysulfide host lattice of the general formula ABOS:M. Furthermore, this invention is related to the use of these phosphors in various technical applications such as fluorescent lamps, colored light or white light emitting LEDs, scanning beam displays working with UV or purple laser as exciting source and other devices in order to convert especially UV or NUV radiation or short-wave visible light into an useful longer-wave visible radiation. This invention is also related to light sources and/or display applications that contain the inventive phosphor.
    Type: Grant
    Filed: March 5, 2009
    Date of Patent: November 27, 2012
    Assignee: Leuchtstoffwerk Breitungen GmbH
    Inventors: Cheng-Jun Duan, Theresia Hubertus Hintzen, Sylke Rösler, Detlef Starick
