Abstract:
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 to said first solution to form CuFeS maintaining said mixture of said first solution and said second solution at said nucleation temperature for a predetermined length of time; after said predetermined length of time, cooling said mixture of said first solution and said second solution to a second temperature that is less than said nucleation temperature; after said mixture reaches said second temperature adding a quenching solvent to said mixture; and purifying said CuFeS
