  • Semiconductor nanocrystals
    Patent number: 10276735
    Abstract: A semiconductor nanocrystal include a first I-III-VI semiconductor material and have a luminescence quantum yield of at least 10%, at least 20%, or at least 30%. The nanocrystal can be substantially free of toxic elements. Populations of the nanocrystals can have an emission FWHM of no greater than 0.35 eV.

  • Copolymer-associated nanomaterial
    Patent number: 8894891
    Abstract: A nanomaterial can include an outer layer including a ligand. The ligand can include a first monomer unit including a first moiety having affinity for a surface of the nanocrystal, a second monomer unit including a second moiety having a high water solubility, and a third monomer unit including a third moiety having a selectively reactive functional group or a selectively binding functional group. The ligand can be a random copolymer.
