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: Collections of phosphor particles have achieved improved performance based on improved material properties, such as crystallinity. Display devices can be formed with these improved submicron phosphor particles. Improved processing methods contribute to the improved phosphor particles, which can have high crystallinity and a high degree of particle size uniformity. Dispersions and composites can be effectively formed from the powders of the submicron particle collections.
