摘要： Metal oxide nanostructure and methods of making metal oxide nanostructures are provided. The metal oxide nanostructures can be 1-dimensional nanostructures such as nanowires, nanofibers, or nanotubes. The metal oxide nanostructures can be doped or un-doped metal oxides. The metal oxide nanostructures can be deposited onto a variety of substrates. The deposition can be performed without high pressures and without the need for seed catalysts on the substrate. The deposition can be performed by laser ablation of a target including a metal oxide and, optionally, a dopant. In some embodiments zinc oxide nanostructures are deposited onto a substrate by pulsed laser deposition of a zinc oxide target using an excimer laser emitting UV radiation. The zinc oxide nanostructure can be doped with a rare earth metal such as gadolinium. The metal oxide nanostructures can be used in many devices including light-emitting diodes and solar cells.

摘要： Embodiments relate to methods of metal oxide nanocrystals preparation. In embodiments, a metal-organic precursor may be economically synthesized by reacting a metal with an organic acid. The organic acid may include an aliphatic chain longer than three carbon atoms. The metal may be In, Sn, Al, Ga, Zn, Cd, Sb, Bi, Ge, Mn, Ti, Nb, V, Cr, Mo, Fe, Y, Mg, Co, as well as mixtures thereof. Further processing of the metal-organic precursor (e.g. by pyrolysis, hydrolysis, or alcoholysis) produces metal oxide nanocrystals of desired characteristics. An metal-organic precursor of indium tin oxide (ITO) may be synthesized by reacting indium metal and tin metal with an organic acid having an aliphatic chain longer than three carbon atoms (e.g. stearic acid) at a temperature above 200° C. Further processing of the resulting metal-organic precursor yields ITO nanocrystals of regular shape, uniform size, and average diameter ranging of between about 1-500 nm.

摘要： The present invention relates to a method for preparing uniform metal oxide nanoparticles. According to the preparation method of the present invention, it is possible to maintain the temperature and pressure inside the reactor in a stable and constant manner by removing water generated in the reaction step for forming metal oxide nanoparticles. Thus, the uniformity of nanoparticles formed is increased, and the reproducibility between batches can be increased even in a repeated process and and a large-scale reaction. Therefore, the preparation method of the present invention can be used to synthesize uniform nanoparticles reproducibly in large quantities.
