A method to fabricate good carbon nanotube (CNT) field emitters using electroless codeposition and CNT purification techniques was developed. Multiwalled CNTs (MWNTs) were codeposited with Ni to form a composite layer acting as the emitter. This composite layer is uniform in thickness and the MWNTs distributed in Ni matrix show a strong adhesion to the substrate. To ensure the emitting quality and good dispersion of MWNTs in the composite, heat annealing and acid immersion process were employed. The composite film shows good emission uniformity and the current density of 1.0 mA/cm(2) was obtained at about 5.7 V/mu m.
