  • Publication number: 20070289491
    Abstract: A semiconductor nanocrystal composition comprising a Group V to VI semiconductor material and a method of making same. The method includes synthesizing a semiconductor nanocrystal core, where the synthesizing includes dissolving a Group V to VI anion gas in a first solvent to produce a Group V to VI anion precursor, preparing a cation precursor, and reacting the Group V to VI anion precursor with the cation precursor in the presence of a second solvent. The reacting may occur in a high pressure vessel.

  • Publication number: 20070221947
    Abstract: A high-refractive index material that includes semiconductor nanocrystal compositions. The high-refractive index material has at least one semiconductor nanocrystal composition incorporated in a matrix material and has a refractive index greater than 1.5. The semiconductor nanocrystal composition has a semiconductor nanocrystal core of a II-VI, III-V, or IV-VI semiconductor material. A method of making a high-refractive index material includes incorporating, at least one semiconductor nanocrystal composition in a matrix material. An application of a high-refractive index material includes incorporating at least one semiconductor nanocrystal composition in a matrix material to form the high-refractive index material and depositing the high-refractive index material on the surface of a lighting device.

  • Publication number: 20060014040
    Abstract: A semiconductor nanocrystal complex including a metal layer formed on the outer surface of a semiconductor nanocrystal core after synthesis of the semiconductor nanocrystal core and a method for preparing a nanocrystal complex comprising forming a metal layer on a semiconductor nanocrystal core after synthesis of the semiconductor nanocrystal core. The metal layer may passivate the surface of the semiconductor nanocrystal core and protect the semiconductor nanocrystal core from the effects of oxidation. Also provided is a semiconductor nanocrystal complex with a shell grown onto the metal layer formed on the semiconductor nanocrystal core. In this embodiment, the metal layer may prevent lattice mismatch between the semiconductor shell and the semiconductor nanocrystal core.
