A thermal chemical vapor deposition (CVD) reactor was built and used to grow vertically and horizontally aligned carbon nanotube arrays. The asgrown nanotubes were investigated on a single tube level using nearinfrared photoluminescence (PL) microscopy and PL excitation spectroscopy as well as Raman, atomic force and scanning electron microscopy. The PL of singlewalled carbon nanotubes (SWNT) in different surroundings and at temperatures down to 4 K was analyzed. Ultralong CVDgrown nanotubes were imaged on Si/SiO2 to determine their chirality and to check structural integrity along the nanotube length. Furthermore, ultralong SWNTs were manipulated (moved, bent and fractured) employing an AFM. Finally, a new approach to determine relative abundances and PL quantum yields of semiconducting SWNTs in dispersions is presented, which is based on statistical counting of individual nanotubes by means of PL spectroscopy.
