摘要

A novel cylinder-shaped structure field emission lighting tube (FELT) was fabricated. As an emission cathode the carbon nanotubes (CNTs) film were grown directly on the tungsten wire by pyrolysis of iron FePc, and were mounted by using elastic assembling technology. The model of electric field of this FELT was established. The electrons emitting characteristics of electronic field was measured. FELT can reach a static brightness of ~1.6 x 10~3 cd/m~2 and can be operated at 180 V. The turn-on field is 0.9 V/μm. When electronic field E = 2.0 V/μm, the current density J = 320 A/m~2.
