Field Emission Properties of CNTs Grown on Graphite Substrates Immersed in Ni(NO3)2 Solution by Chemical Vapor Deposition at Different Growth Temperatures
Carbon nanotubes (CNTs) were synthesized on graphite substrates immersed in 0.5 MNi(NO3)2 solution by low pressure chemical vapor deposition (LFCVD) at different temperatures. The influence of growth temperature ranged from 500℃ to 700℃ on the field emission (FE) properties of the CNTs was studied. Scanning electron microscope (SEM) and Raman spectroscopy measurements indicated that the diameters of the CNTs and intensity ratio of G and D bands (I (D)/I(G)) decreased with the increase of the growth temperature. The full width at half maximum (FWHM) of G peak which also decreased with increasing of the growth temperature showed the enhancement of the graphitization of CNTs. And it is found that the field emission property of the CNTs was dependant on the growth temperature.
