Ag/ZnO nanocables synthesized under different conditions. (a,b,c,d) SEM images of the products obtained using ZnO and AgNO₃ as the source at reaction temperatures of 1,250°C, 1,280°C, 1,290°C, and 1,320°C, respectively. The inset in (c) is a higher magnification image. (e,f) SEM images of the products with AgNO₃ of 0.25 and 0.1 g, respectively. The inset in (e) is a TEM image, and the inset in (f) is a higher magnification SEM image.
