摘要

Titanium dioxide nanotubes were prepared by refluxing TiO₂ in 10 M NaOH at 200 °C for 12 h. The light absorption edge was slightly shifted to a longer wavelength when 0.025 mol % of iron was incorporated to TiO ₂ nanotubes. A turn-on field at 12 V/μm and a maximum current density of 12 mA/ cm² at 19 V/μm was observed for the Fe-doped but not for pure TiO₂. The field emission behavior can be correlated with the geometry and electronic states of the nanotubes.
