ABSTRACT

ZnO nanowires were synthesized by the thermal evaporation method and their growth mechanisms were confirmed by the characterization of the structural features depending on the growth conditions. The increase of vaporization temperature accelerates the growth rate and morphologies of ZnO nanowires were drastically changed at the temperature over 1000℃, because of changed CO/CO₂ partial pressure. Au particles play their role on growth of ZnO nanowire as catalyst at growth temperature over 700℃. The synthesized ZnO nanowires exhibit blue emission at 380 nm.
