Precise Raman measurements of C 60 fullerene nanowhiskers synthesized using the liquid-liquid interfacial precipitation method

Abstract

Raman measurements and uncertainty evaluations were conducted for C60 fullerene nanowhiskers (C60FNWs) synthesized using the liquid-liquid interfacial precipitation (LLIP) method and for a vacuum-deposited C60 thin film. No photopolymerization was observed for the C60 molecules when the specimens were irradiated by a green laser of 532 nm wavelength at a power density of 5.7×10 3 mW/mm 2 . It is demonstrated that the 1469.95 ± 0.42 cm -1 can be used as a standard peak position of the Ag(2) mode of C60FNWs.
