    摘要: Polymer-inorganic particle blends are incorporated into structures generally involving interfaces with additional materials that can be used advantageously for forming desirable devices. In some embodiments, the structures are optical structures, and the interfaces are optical interfaces. The different materials at the interface can have differences in index-of-refraction to yield desired optical properties at the interface. In some embodiments, structures are formed with periodic variations in index-of-refraction. In particular, photonic crystals can be formed. Suitable methods can be used to form the desired structures.

    摘要: A collection of nanoparticles of aluminum oxide have been produced by laser pyrolysis have a very narrow distribution of particle diameters. Preferably, the distribution of particle diameters effectively does not have a tail such that almost no particles have a diameter greater than about 4 times the average diameter. The pyrolysis preferably is performed by generating a molecular stream containing an aluminum precursor, an oxidizing agent and an infrared absorber. The pyrolysis can be performed with an infrared laser such as a CO2 laser.

    摘要: Functional composite materials comprise elemental inorganic particles within an organic matrix. The elemental inorganic materials generally comprise elemental metal, elemental metalloid, alloys thereof, or mixtures thereof. In alternative or additional embodiments, the inorganic particles can comprise a metal oxide, a metalloid oxide, a combination thereof or a mixture thereof. The inorganic particles can have an average primary particle size of no more than abut 250 nm and a secondary particle size in a dispersion when blended with the organic matrix of no more than about 2 microns. The particles can be substantially unagglomerated within the composite. The organic binder can be a functional polymer such as a semiconducting polymer. The inorganic particles can be surface modified, such as with a moiety having an aromatic functional group for desirable interactions with a semiconducting polymer. Appropriate solution based methods can be used for forming the composite from dispersions of the particles. The composites can be processed into products, such as printed electronics devices.
