Figure 7
The overview FESEM images for different growth times and AgNO3 concentrations.
(a)–(d) are images for the 0.001 mol/L AgNO3 concentration. (e)–(h) are for the 0.01 mol/L AgNO3 concentration. (i)–(l) are for the 0.1 mol/L AgNO3 concentration. (m)–(p) are for the 0.2 mol/L AgNO3 concentration. The four columns, from left to right, are for 5, 10, 15 and 30 minutes of growth time. The two scale bars are 500 nm for (a)–(h) and 5 μm for (i)–(p).
