Paper Abstract

Angular dependence of X-ray emission and absorption spectra was measured for both graphite and films of carbon nanotubes (CNTs) oriented perpendicular to the substrate surface. The ratio of intensities of Π and σ peaks in the X-ray spectra of CNT films was found to depend not only on the orientation of nanotubes but also on the orientation of graphite-like layers inside multi-walled nanotubes. Fluorescence measurement for the samples also showed the dependence on the degree of CNT alignment as well as on the texture of CNT layers. A possibility of X-ray photon propagation in CNTs in the conditions of anomalous dispersion near the C K-edge is discussed.
