摘要: Vanadium oxide nanoparticles were produced with vanadium in a variety of oxidation states and with different crystalline lattice structures. These particles preferably have an average diameter of 150 nm or less with a narrow distribution of diameters. The particles manifest unique properties that result from the small particle size and correspondingly large surface area. A variety of the vanadium oxide nanoparticles can be produced by a versatile laser pyrolysis arrangement. These nanoparticles can be further processed to change the properties of the particles without destroying the nanoscale size of the particles.

摘要: The stoichiometry and/or crystal structure of vanadium oxide particles are altered by heating initial particles of vanadium oxide under mild conditions. The temperature is generally at least about 300.degree. C. less than the melting point of both the initial vanadium oxide particle and the product vanadium oxide particles. Preferred initial particles are vanadium oxide nanoparticles. The heating can be performed under an oxidizing atmosphere or an inert atmosphere, depending on the particular initial particles and the desired product particles.

摘要: A collection of zinc oxide nanoparticles have been produced by laser pyrolysis. The zinc oxide nanoparticles have average particle diameters of less than about 95 nm and a very narrow particle size distribution. The laser pyrolysis process is characterized by the production of a reactant stream within the reaction chamber, where the reactant stream includes a zinc precursor and other reactants. The zinc precursor can be delivered as an aerosol.

摘要: A collection of nanoscale particles are a composite of carbon and metal oxide or silicon oxide. The composite particles have an average diameter from about 5 nm to about 1000 nm, and can be produced by laser pyrolysis. The laser pyrolysis involves the formation of a molecular stream including a metal precursor, an infrared absorber, an oxidizing agent and a carbon precursor. The pyrolysis is driven by heat absorbed from a laser beam. Furthermore, nanoparticles including titanium oxide with a rutile crystal structure have been produced.

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.
