- Abstract
It was reported that gold nanorods (Au NRs), synthesized by the conventional seed-mediated method, show unusual photoresponse to UV illumination due to the presence of silver nanoclusters (Ag NCs) which etch away Au NRs to slowly shred them and make them shorter in length. Here we report the electrochemical experiments supporting this atypical behavior. These studies show that a redox reaction is taking place on the surface of Au NRs in the presence of excited Ag NCs. The excitation energy of Ag NCs can be released in the system as the flow of free charges and it can be utilized for a photosensitive electronic application. A NC-sensitized photovoltaic cell shows the possibility of conversion (with 0.17% efficiency) from UV radiation to electrical energy based on Ag NCs.
