  • Patent number: 7914710
    Abstract: Method for the preparation of inorganic-NP-composite microgels is based on the reversible transfer of microgels between water and an organic solvent such as tetrahydrofuran (THF). The method is used to produce semiconductor nanocrystals, often referred to as quantum dots (QDs) which are well known for their unique optical, electrical, magnetic and catalytic properties, as the inorganic NPs, recognizing that the best quality QDs are synthesized by a high temperature process in organic media, and have their surface covered with hydrophobic ligands (such as trioctylphosphine oxide, TOPO) that render the NPs insoluble in an aqueous solution.

Nanowires can intersect to form networks and can be covalently bonded at points of intersection. Disclosed nanowire networks can be substantially uniform and can form an ordered network. Nanowire networks can be used to fabricate electronic and optical devices.

  • Publication number: 20080237549
    Abstract: A novel phosphor material which can be manufactured without utilizing a fault formation process which is difficult to be controlled. The phosphor material has a eutectic structure formed of a base material that is a semiconductor formed of a Group 2 element and a Group 6 element, a semiconductor formed of a Group 3 element and a Group 5 element, or a ternary phosphor formed of an alkaline earth metal, a Group 3 element, and a Group 6 element, and a solid solution material including a transition metal. The phosphor material is suited for an EL element because of less variation of characteristic since defect formation process in which stress is applied externally to form a defect inside of a phosphor material is not needed.

    Abstract: A method for the non-catalytic growth of nanowires is provided. The method includes a reaction chamber with the chamber having an inlet end, an exit end and capable of being heated to an elevated temperature. A carrier gas with a flow rate is allowed to enter the reaction chamber through the inlet end and exit the chamber through the exit end. Upon passing through the chamber the carrier gas comes into contact with a precursor which is heated within the reaction chamber. A collection substrate placed downstream from the precursor allows for the formation and growth of nanowires thereon without the use of a catalyst. A second embodiment of the present invention is comprised of a reaction chamber, a carrier gas, a precursor target, a laser beam and a collection substrate. The carrier gas with a flow rate and a gas pressure is allowed to enter the reaction chamber through an inlet end and exit the reaction chamber through the exit end.

  • Publication number: 20080157032
    Abstract: There has been a problem in that kinds of conventional light-emitting materials are not sufficient; therefore, choices of materials and manufacturers of light emitting materials are limited, resulting in an expensive light-emitting device. The present invention provides a novel method for manufacturing a light-emitting material suitable for mass production that can be manufactured at a low cost, and a novel light-emitting material which can provide light emission with high intensity. A mixture in which CuAlS2 is added in a small amount into ZnS as a base material is put in a reaction container. Then, the reaction container is hermetically sealed and the mixture is baked. Note that the reaction container is preferably hermetically sealed in a state where a reduced pressure is held in the reaction container. Further, in a light-emitting element using a light-emitting material obtained, electroluminescence with high luminance can be obtained.
