Novel [60]fullerene–silver nanocomposite with large optical limiting effect

A novel [60]fullerene–Ag nanocomposite (DTC60–Ag) is prepared by the in situ reduction of silver ions encapsulated in a new mono-functionalized methano-[60]fullerene derivative (DTC60) with reverse micelle-like structure. The formation and size of the nanocomposite has been determined from the UV–Vis plasmon absorption band, FT-IR spectra method and transmission electron microscopic (TEM) analysis. The average size distribution is about 5.2 mm. The optical limiting properties of DTC60 and DTC60–Ag are measured via a nanosecond Nd:YAG pulse laser system at a wavelength of 532 nm. The experimental results demonstrate that the optical limiting behavior of DTC60–Ag is better than that of both C60 and DTC60.
