摘要：

Optical absorption spectra have been measured for hexagonal boron nitride (h-BN), rhombohedral BN (rh-BN), and material obtained by laser vaporization of BN target under a nitrogen atmosphere and contained single-wall BN-nanotues. Band gap of the BN materials was found to have a value of 6.0-6.3 eV. The spectra of h-BN and vaporized material exhibited a peak at similar to 5.5 eV, moreover, the latter sample showed an absorption band around 4.5 eV. The vaporized material has been fractionated to the BN-platelets and single-wall BN-nanotubes. Absorption peaks, located bellow the bottom the conductance band, were found to be characteristics of thin BN-platelets and they could be attributed to defects in BN network.
