通过化学气象沉积的方法用甲烷作为碳源在金属钨作为衬生长的碳纳米管,我们能发现碳纳米管与催化溶液(Fe(NO3)3·9H2O)在 2.5 摩尔的浓度.在金属钨做衬底的碳纳米管的场发射电流可以达到 100 微安时场发射增强因子大约为5008.通过用一个简单的玻璃真空管结构作为真空腔,我们可以证明场发射发光管和研究这个发光器件的特性.这个发现为制作一种新型的无汞的持久的发光器件成为可能而且有很高的发光性能.

Carbon nanotubes (CNTs) have been grown on tungsten wires via catalytic thermal chemical va-por deposition (CVD) with methane as the source of carbon atoms. On the tungsten wire, we could find the CNTs with catalyst solution (Fe(NO3)3. 9H2O) at 2.5 mole concentration (mol/L). A field emission current of 100 Μa can be obtained of CNTs on tungsten and the field enhancement factor was then esti-mated to be 5008. By using a simple structure of vacuum glass tube as the vacuum chamber, we could dem-onstrate a field emission lighting tube and investigate the characteristics of the lighting device. The notion is highly potential for making a new lighting device which is mercury-free, continuously luminous and has a high luminance capability.
