Abstract
Official abstract text for this publication.
A method of forming CuFeS 2 chalcopyrite nanoparticles. The method includes, in the presence of one or more ligands, reacting an iron-containing compound, a copper-containing compound and a sulfur-containing compound to form CuFeS 2 chalcopyrite nanoparticles; and wherein at least one of the ligands forms a coordination complex with copper, and at least one of the ligands forms a coordination complex with iron. Also a method of forming metal-doped CuFeS 2 chalcopyrite nanoparticles such as Zn-doped CuFeS 2 chalcopyrite nanoparticles. Also, a CuFeS 2 chalcopyrite nanoparticle layer on a substrate. Also, a composition of matter including Zn-doped CuFeS 2 chalcopyrite nanoparticles. Also, a Zn-doped CuFeS 2 chalcopyrite nanoparticle layer on a substrate.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: forming an anhydrous first solution of an iron-containing compound and a copper-containing compound in a first solvent, said first solvent including one or more primary alkyl amines; forming a second anhydrous solution of a sulfur-containing compound in a second solvent, said second solvent including one or more alkyl amines; heating said first solutions to a nucleation temperature; after said heating, adding said second solution…
