  • Display devices comprising green-emitting quantum dots and red KSF phosphor
    Patent number: 11043618
    Abstract: LED devices emitting white light comprise a blue-emitting LED, green-emitting quantum dots (QDs) and red-emitting K2SiF6:Mn4+ (KSF) phosphor. A backlight unit (BLU) for a liquid crystal display (LCD) comprises one or more blue-emitting LEDs and a polymer film containing green-emitting QDs and KSF phosphor. The QDs and/or KSF phosphor may be encapsulated in beads that provide protection from oxygen and/or moisture.
    Type: Grant
    Filed: March 1, 2019
    Date of Patent: June 22, 2021

  • Shelling of halide perovskite nanoparticles for the prevention of anion exchange
    Patent number: 10796901
    Abstract: A core/shell semiconductor nanoparticle structure comprises a core comprising a halide perovskite semiconductor and a shell comprising a semiconductor material that is not a halide perovskite (and that is substantially free of halide perovskites). The halide perovskite semiconductor core may be of the form AMX3, wherein: A is an organic ammonium such as CH3NH3+, (C8H17)2(CH3NH3)+, PhC2H4NH3+, C6H11CH2NH3+ or 1-adamantyl methyl ammonium, an amidinium such as CH(NH2)2+, or an alkali metal cation such as Li+, Na+, K+, Rb+ or Cs+; M is a divalent metal cation such as Mg2+, Mn2+, Ni2+, Co2+, Pb2+, Sn2+, Zn2+, Ge2+, Eu2+, Cu2+ or Cd2+; and X is a halide anion (F?, Cl?, Br?, I?) or a combination of halide anions.
