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。
Methods of Chemical Meteorological Deposition Using Methane as a Carbon Source In a metal tungsten as a carbon nanotube-grown carbon nanotube, we can find that the carbon nanotube is at a 2.5 molar concentration with a catalytic solution (Fe (NO3) 3 · 9H2O). The field emission enhancement factor of carbon nanotubes with metal tungsten substrate up to 100 microamps is about 5008. By using a simple glass vacuum tube structure as a vacuum chamber, we can demonstrate field emission tubes and study the characteristics of this light emitting device. This discovery makes it possible to produce a new mercury-free, long-lasting light-emitting device with high luminous performance.
