Highly ordered TiO{sub 2}/Ti nanotube arrays were fabricated by anodic oxidation method in 0.5 wt% HF. Using prepared TiO{sub 2}/Ti nanotube arrays deposited Ni nanoparticles as substrate, high quality diamond-like carbon nanorods (DLCNRs) were synthesized by a conventional method of chemical vapor deposition at 750 deg. C in nitrogen atmosphere. DLCNRs were analyzed by filed emission scanning electron microscopy and Raman spectrometer. It is very interesting that DLCNRs possess pagoda shape with the length of 3-10 {mu}m. Raman spectra show two strong peaks about 1332 cm{sup -1} and 1598 cm{sup -1}, indicating the formation of diamond-like carbon. The field emission measurements suggest that DLCNRs/TiO{sub 2}/Ti has excellent field emission properties, a low turn-on field about 3.0 V/{mu}m, no evident decay at 3.4 mA/cm{sup 2} in 480 min.
