Abstract
Official abstract text for this publication.
The present invention provides a method of preparing aluminum-doped zinc oxide (AZO) nanocrystals. In an exemplary embodiment, the method includes (1) injecting a precursor mixture of a zinc precursor, an aluminum precursor, an amine, and a fatty acid in a solution of a vicinal diol in a non-coordinating solvent, thereby resulting in a reaction mixture, (2) precipitating the nanocrystals from the reaction mixture, thereby resulting in a final precipitate, and (3) dissolving the final precipitate in an apolar solvent. The present invention also provides a dispersion. In an exemplary embodiment, the dispersion includes (1) nanocrystals that are well separated from each other, where the nanocrystals are coated with surfactants and (2) an apolar solvent where the nanocrystals are suspended in the apolar solvent. The present invention also provides a film. In an exemplary embodiment, the film includes (1) a substrate and (2) nanocrystals that are evenly distributed on the substrate.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: injecting a precursor mixture comprising a zinc precursor, an aluminum precursor, an amine, and a fatty acid into a solution of a vicinal diol and a non-coordinating solvent to produce a reaction mixture, wherein the non-coordinating solvent is selected from a group consisting of octadecene, benzylether, and phenylether; precipitating aluminum-doped zinc oxide nanocrystals from the reaction mixture to form a final precipitate; and di…
