Abstract
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.
Claims10
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.
