Figure 1.

a SEM image, b XRD spectrum and c XPS spectrum of P-doped ZnO nanowires. The inset of b shows the detail of the peaks suppressed by (002) peak d Low-magnification TEM image and e HRTEM image of a typical P-doped ZnO nanowire. Inset of e: electron diffraction pattern of the nanowire f EDS spectrum of an individual P-doped ZnO nanowire.
