Effect of an oxidizing environment on the phase structure of lead oxide nanowires

The effect of an oxidizing environment on the phase formation of lead oxide nanowires is reported. The phase structure, optical properties, sizes and morphologies of the nanowires have been investigated by atomic force microscopy, x-ray diffraction, and UV—Vis-NIR reflectance diffusion spectrums. The phase structure of the lead oxide nanowires is very sensitive to both the process temperature and the oxygen flow/oxygen partial pressure. Single phase oxide nanowires can be obtained only in a narrow, low temperature range and within a low oxygen partial pressure. The wire morphology of Pb nanowires has been perfectly maintained after being oxidized.
