20140249324 | Copper-Indium-Gallium-Chalcogenide Nanoparticle Precursors for Thin-Film Solar Cells - Nanoparticles containing IUPAC group 11 ions, group 13 ions and sulfur ions are synthesized by adding metal salts and an alkanethiol in an organic solvent and promoting the reaction by applying heat. Nanoparticles are formed at temperatures as low as 200° C. The nanoparticles may be thermally annealed for a certain amount of time at a temperature lower than the reaction temperature (usually ˜40° C. lower) to improve the topology and narrow the size distribution. After the reaction is complete, the nanoparticles may be isolated by the addition of a non-solvent and re-dispersed in organic solvents including toluene, chloroform and hexane to form a nanoparticle ink. Additives may be incorporated in the reaction solution to tailor the final ink viscosity. | 09-04-2014 |

20150076494 | Synthesis of Metal Oxide Semiconductor Nanoparticles from a Molecular Cluster Compound - A method of preparing metal oxide nanoparticles is described herein. The method involves reacting nanoparticle precursors in the presence of a population of molecular cluster compounds. The molecular cluster compound may or may not contain the same metal as will be present in the metal oxide nanoparticle. Likewise, the molecular cluster compound may or may not contain oxygen. The molecular cluster compounds acts a seeds or templates upon which nanoparticle growth is initiated. As the molecular cluster compounds are all identical, the identical nucleation sites result in highly monodisperse populations of metal oxide nanoparticles. | 03-19-2015 |
