Abstract:
Well-aligned ZnO nanorod arrays had been prepared by hydrothermal methods assisted with pulsed electromagnetic field (PEMF). The effects of pulsed electromagnetic field on growth and structure properties of ZnO nanorod arrays were studied in detail. XRD and SEM analysis showed ZnO nanorod arrays had bigger length to diameter ratio and better verticality on the substrate. And the Raman analysis showed well-aligned ZnO nanorod arrays have highly crystallized wurtzite structure with much fewer defects after a pulsed electromagnetic field was introduced. At last, a possible mechanism of pulsed electromagnetic field acted on nanorod arrays was proposed.
