Nanowire preparation methods, compositions, and articles

摘要

Preparation methods, compositions, and articles useful for electronic and optical applications are disclosed. Such methods reduce metal ions to metal nanowires in the presence of bromide ions, IUPAC Group 14 elements in their +2 oxidation state, and optionally chloride ions. The product nanowires are useful in electronics applications.

1. A method comprising:
providing at least one first composition comprising a first molar quantity of at least one first reducible metal ion; and reducing the at least one first reducible metal ion to at least one first metal nanowire in the presence of at least one bromide ion, at least one chloride ion, and a second molar quantity of at least one second metal ion comprising at least one tin ion, wherein the ratio of the second molar quantity to the first molar quantity is from about 0.0001 to about 0.1.
