| 20110135928 | METAL SILICON NITRIDE OR METAL SILICON OXYNITRIDE SUBMICRON PHOSPHOR PARTICLES AND METHODS FOR SYNTHESIZING THESE PHOSPHORS - Submicron powders of metal silicon nitrides and metal silicon oxynitrides are synthesized using nanoscale particles of one or more precursor materials using a solid state reaction. For example, nanoscale powders of silicon nitride are useful precursor powders for the synthesis of metal silicon nitride and metal silicon oxynitride submicron powders. Due to the use of the nanoscale precursor materials for the synthesis of the submicron phosphor powders, the product phosphors can have very high internal quantum efficiencies. The phosphor powders can comprise a suitable dopant activator, such as a rare earth metal element dopant. | 06-09-2011 |
| 20090255189 | ALUMINUM OXIDE PARTICLES - 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 CO | 10-15-2009 |
