Fabrication of Highly Photoluminescent Gold(I) Nanorods and their Electrophoretic Patterning

Fabrication of nanorods (NRs) composed of a cationic Au(I) complex was demonstrated by means of the solution-injection method. A colloidal solution of the NRs showed brilliant bluish green photoluminescence with a quantum yield as high as 58%. The NRs were found to be 100–400 nm in width and 3–5 μm in length by transmission electron microscopy observations. Pattern formation of the NRs was achieved successfully after a selective electrophoretic deposition onto an indium tin oxide coated glass substrate, which maintains a relatively high luminescence quantum yield.
