| Abstract: |
| [Objective] In this paper, ZnO nanowires were synthesized on ITO conductive glasses by chemical bath deposition.[Methods] The parameters of processing ZnO nanowires were systematically investigated, including the crystallinity of ZnO seed layers, PEI concentration. The morphology and crystal structure of ZnO nanowires were characterized by SEM, XRD, AFM.[Results] ZnO nanowires were vertically grown on ITO substrate and hexagonal wurtzite structure when the temperature was 200℃.Moreover, we obtained ZnO nanowires with aspect ratio of 20.56 at the PEI concentration of 4.5 mmol/L.[Conclusion] The prepared ZnO nanowires have good orientation, uniform size and high aspect ratio. |
