Electrodeposition of Au/Brush-Zn Heterojunction Nanowires
Au/brush-Zn heterojunction nanowires were synthesized by using the Anodic Alumina Membrane (AAM) template combine with DC electrodeposition. As-prepared Au/brush-Zn nanowires were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy dispersive x-ray spectrometer (EDS). Secondary growth mechanism is proposed for the formation of Zn brush structure. The Au/brush-Zn nanowires exhibit a strong absorption in a broad range of wavelength especially between 200 and 360nm, which may be ascribed to the transition of the electrons from the d band to the s, p conduction band near the Fermi surface and the transition from valence bands to conduction bands for Zn brush associated with enhancement of Au.
