| Popis: | The authors have developed a spherical field-emission cathode based on carbon nanotube paste. The cathode was formed on a 2mm stainless-steel ball with a silver paste sublayer which provide good adhesion between carbon nanotubes and the metal substrate. The emission current with a density of 300mA∕cm2 was obtained and the current showed good stability. The cathode was assembled into a luminescent lightbulb with 8kV anode voltage. The luminous efficiency was 26.4lm∕W on pulse mode. |
