Kurzfassung:
The semiconductivity of carbon nanotubes has been investigated by the luminescence measurement. The nanotubes were characterized by scanning electron microscopy and X-ray diffraction. Carbon nanotubes can luminesce under laser irradiation. Using the photoluminescence measurements the emission spectrum is very wide near the infrared emission range, with a major peak at 1.3 eV. According to the temperature dependence of the photoluminescence and the thermal photoluminescence experiments, the luminescence of carbon nanotubes comes from the center of the energy trap of a defect. In view of this result, it is suggested that the technique of thermal stimulated luminescence provides a simple alternative method to obtain the energy levels in carbon nanotubes systems.
