Electrodeposition Growth of Vertical ZnO Nanorod/Polyaniline Heterostructured Films and Their Optical Properties

Vertical ZnO nanorods/polyaniline (NRs/PAN) heterostructured films have been fabricated by a facile electrochemical deposition process and characterized by AFM, TEM, XRD, and photoluminescence spectroscopy. The predeposited PAN thin film on ITO substrates possesses porous surface morphology, which acts as a significant template-like function on the subsequent growth of ZnO NR arrays. The ZnO NRs on PAN exhibit excellent features, including good crystallinity, metal catalyst-free process, and strong ultraviolet (UV) photoluminescence, indicating potential applications in relevant optoelectronics devices.
