Method for the formation of PbSe nanowires in non-coordinating solvent

摘要

This disclosure concerns a method of making nanowires in a single flask and in non-coordinating solvent involving the reaction of PbO with oleic acid to produce Pb oleate, heating the Pb oleate to a preferred temperature with additional coordinating ligands, injecting a solution of Se to produce a second solution, heating the second solution, and maintaining the temperature, resulting in nucleation and growth of PbSe nanowires.

主权项

1. A method of making nanowires comprising:
reacting PbO with oleic acid in a non-coordinating solvent and producing Pb oleate in a flask; heating the Pb oleate to between 225° C. and 275° C. under inert gas; injecting a first solution of Se dissolved in trialkylphosphine into the flask and producing a second solution; heating the second solution; maintaining the temperature greater than 200° C. in the flask; and resulting in PbSe nanowires.
