Comparative spectroscopic characterization of fullerene nanomaterials

Abstract

The higher fullerenes C76-D2 and C84-D2:22, as well as the basic fullerenes C60 and C70 were chromatographically isolated from carbon soot and the fullerol C60(OH)24 was synthesized, using new and advanced methods and processes. Their FT-IR(KBr) and electronic absorption spectra were recorded. All the observed infrared and UV/VIS bands are in excellent agreement with the theoretical calculations for these molecules. The molar absorptivity, as well as the integrated molar absorptivity of the absorption bands of the obtained fullerene nanomaterials was determined. These results are significant for their identification and quantitative determination either in natural resources or in artificially synthesized materials, electronic and optical devices, polymers, sensors, diagnostic and therapeutic agents, solar cells, nanophotonic lenses with optical absorption properties closer to human eye light sensitivity that can be used for early diagnosis of diabetes, in applied optical science, biomedical engineering and industry etc.
