Amorphous diamond nanorod arrays with excellent field emitting have been fabricated firstly on the AAO template by the filtered cathodic arc plasma technique. Microscopic analysis has displayed that the nanorods are very uniformly distributed, and the density is very high up to ～109 cm-2. The nanorod arrays are found to have an extremely low turn-on field of 0.16 V/μm, which is lower than other reported materials, and a high- emission current density of 180 mA/cm2 under an applied field of 2 V/μm can also be obtained. Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and filed emitting tester are employed to characterize the nanorod arrays. The field emission mechanism of the nanorod arrays is also discussed.
