•Gold nanorods were grown on ITO substrate by electrochemical deposition of gold seeds.•Growth of GNRs was observed within 4 h on indium–tin-oxide substrate.•Increasing the silver ion concentration increases the yield of GNRs on ITO substrate.•GNR growth was also observed in solution but with poor yield.•GNRs on ITO substrate showed shape dependent SERS enhancements.
Growth of gold nanorods (GNRs) on indium–tin-oxide (ITO) substrate was achieved within 4 h using in-situ electrochemical reduction of Au+ ions from the growth solution. The electrochemically deposited gold nanoparticles on ITO substrate act as the seeds for the growth of GNRs. The yield of GNRs on ITO substrate increases with increasing the concentration of Ag+ ions in growth solution. Further, the GNRs grown on ITO substrate showed shape dependent surface enhanced Raman scattering enhancement towards 4-aminothiophenol adsorbed on GNR surface.
