中文摘要	Well-aligned TiO2/Ti nanotube arrays were synthesized by anodic oxidation of titanium foil in 0.5 wt.% HF in various anodization voltages. The images of ﬁled emission scanning electron microscopy indicate that the nanotubes structure parameters, such as diameter, wall thickness and density, can be controlled by adjusting the anodization voltage. The peaks at 25.3° and 48.0° of X-ray diffraction pattern illuminate that the TiO2 nanotube arrays annealed at 500 °C are mainly in anatase phase. The ﬁled emission (FE) properties of the samples were investigated. A turn-on electric ﬁeld 7.8 V/µm, a ﬁeld enhancement factors approximately 870 and a highest FE current density 3.4 mA/cm2 were obtained. The emission current (2.3 mA/cm2 at 18.8 V/ µm) was quite stable within 480 min. The results show that the FE properties of TiO2/Ti have much relation to the structure parameters.
