Figure 6

SEM and TEM images of pure SnO₂ nanorods and Zn-doped SnO₂ nanorods. ((a), (b)) SEM image of pure SnO₂ nanorods, ((c), (d)) SEM image of Zn-doped SnO₂ nanorods, (e) TEM image, and (f) HRTEM image of a typical nanorod. Inset in (f) is the fast Fourier transform (FFT) of the HRTEM image adapted from [14] with permission.
