Figure 2From: Gold nanonetwork film on the ITO surface exhibiting one-dimensional optical propertiesOptical absorption spectra. Gold nanostructures on the surface prepared using several Ag+ concentrations, namely (a) 0, (b) 10, (c) 20, (d) 30, (e) 40 and (f) 50 μM. Other reagents were kept unchanged as that in Figure 1. Growth time was 4 h.Back to article page
