摘要： Surface-modified nanoparticles are produced by associating ligand interactive agents with the surface of a nanoparticle. The ligand interactive agents are bound to surface modifying ligands that are tailored to impart particular solubility and/or compatibility properties. The ligand interactive agents are crosslinked via a linking/crosslinking agent, such as hexamethoxymethylmelamine or a derivative thereof. The linking/crosslinking agent may provide a binding site for binding the surface modifying ligands to the ligand interactive agents.

摘要： A hybrid organic/inorganic quantum dot composite with high reliability is disclosed. The hybrid organic/inorganic quantum dot composite includes quantum dot, polymer resin, and silica, in which the silica is formed in the polymer resin, one end of the polymer resin forms a chemical bond with the quantum dot, and another end of the polymer resin includes a functional group capable of forming an additional chemical bond. The hybrid organic/inorganic quantum dot composite is resistant to moisture and oxygen permeation, and thus, it is not degraded easily by bonding oxygen and moisture to quantum dots even if moisture and oxygen permeate into the composite. The quantum dot composite may be used as a secondary raw material capable of being processed into another form while maintaining physical properties of quantum dots as a primary raw material.

摘要： Quantum dot semiconductor nanoparticle compositions that incorporate ions such as zinc, aluminum, calcium, or magnesium into the quantum dot core have been found to be more stable to Ostwald ripening. A core-shell quantum dot may have a core of a semiconductor material that includes indium, magnesium, and phosphorus ions. Ions such as zinc, calcium, and/or aluminum may be included in addition to, or in place of, magnesium. The core may further include other ions, such as selenium, and/or sulfur. The core may be coated with one (or more) shells of semiconductor material. Example shell semiconductor materials include semiconductors containing zinc, sulfur, selenium, iron and/or oxygen ions.

摘要： A backlight unit 12 includes LEDs 17, a light guide plate 19 including a light entry end surface 19b, a light output plate surface 19a, and an opposite plate surface 19c, a wavelength conversion sheet 20, and a reflection sheet 25. The light guide plate 18 includes a parallel plate surface 27 on a central portion of the opposite plate surface 19c and parallel with the light output plate surface 19a, and an inclined plate surface 28 on a part of the outer peripheral side portion and being inclined with respect to the light output plate surface 19a to be closer to the light output plate surface 19a as is closer to the outer peripheral end surface. The wavelength conversion sheet 20 overlaps the light output plate surface 19a and contains a phosphor that wavelength-converts the light from the LEDs 17. The reflection sheet 25 overlaps the opposite plate surface 19c and reflects light, and includes a parallel reflection portion 29 along the parallel plate surface 27, and an inclined reflection portion 30 along the inclined plate surface 28.
