Abstract

Crystalline fullerene C₆₀ nanotubes were prepared simply via liquid-liquid interfacial precipitation using the mixture of C₆₀-saturated pyridine and isopropyl alcohol. C₆₀-saturated pyridine solution was exposed to visible light to promote the growth of fullerene C₆₀ nanotubes. The average diameters of the fullerene particles in C₆₀-pyridine colloid solution after irradiation were characterized by dynamic light scattering. After light irradiation, an outer separated layer of pyridine surrounds the fullerene particles because of the charge transfer complexes formation. The mean ratios of inner diameter to outer diameter of fullerene C₆₀ nanotubes fabricated at different irradiation time and wavelength were given in this paper for the first time. On the basis of the relationship between the average diameters of the fullerene particles in C₆₀-pyridine colloid solution and the mean ratio of inner diameter to outer diameter of FNTs fabricated after irradiation, outer separated layer of pyridine surrounding the fullerene particles was supposed to play an important role in the formation process of fullerene C₆₀ nanotubes.
