A field-emission cathode ray tube (FE-CRT) has been fabricated using a unique nanostructure carbon electron emitter called carbon nanometer electron exit (CNX) which has been developed on stainless rod substrate with a special plasma chemical vapor deposition technique. Field emission from CNX has been investigated in a vacuum of 3×106Torr by using a diode configuration with a 5mm diameter anode and an A-K gap of 1mm, which shows that a emission current density of 1mAcm2 can be obtained at an electrical field of 0.95Vμm. When the electrical field was increased to 2.4Vμm, an emission current density of 1.568Acm2 was observed. Scanning electron microscopy images and micro-Raman spectrum were used to characterize the CNX film. The design of the emission system of electronic gun was optimized by simulating the equal-potential lines using a commercial software. Finally, a 4.5in. FE-CRT with a specially designed emission system has been fabricated.
