Abstract: Carbon nanotubes are very typical nanomaterials, because the electron π of carbon nanotubes is restricted by the quantum size, the energy bands of the electron π are discontiguous and the characteristic of its energy level is divisive. The electron π can absorb the photon and makes transition from low energy level to high energy level, so it has the characteristic of wave-absorption . Based on the theory of quantum mechanics and the atomic structure of carbon nanotubes, the electronic energy bands and absorption spectrum of carbon nanotubes are analyzed in this paper, the results show that carbon nanotubes of different size correspond with absorption spectrum of different wave bands, and the computational results are afforded for the bases of designing wave-absorption materials.
