Abstract: Silicon nanoparticle inks provide a basis for the formation of desirable materials. Specifically, composites have been formed in thin layers comprising silicon nanoparticles embedded in an amorphous silicon matrix, which can be formed at relatively low temperatures. The composite material can be heated to form a nanocrystalline material having crystals that are non-rod shaped. The nanocrystalline material can have desirable electrical conductive properties, and the materials can be formed with a high dopant level. Also, nanocrystalline silicon pellets can be formed from silicon nanoparticles deposited form an ink in which the pellets can be relatively dense although less dense than bulk silicon. The pellets can be formed from the application of pressure and heat to a silicon nanoparticle layer.

Abstract: 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.

Abstract: High rate deposition methods comprise depositing a powder coating from a product flow. The product flow results from a chemical reaction within the flow. Some of the powder coatings consolidate under appropriate conditions into an optical coating. The substrate can have a first optical coating onto which the powder coating is placed. The resulting optical coating following consolidation can have a large index-of-refraction difference with the underlying first optical coating, high thickness and index-of-refraction uniformity across the substrate and high thickness and index-of-refraction uniformity between coatings formed on different substrates under equivalent conditions. In some embodiments, the deposition can result in a powder coating of at least about 100 nm in no more than about 30 minutes with a substrate having a surface area of at least about 25 square centimeters.
