Abstract: Nano-structured Onion-like Fullerenes(NSOFs) were synthesized by DC arc-discharge. Soots in different regions of oven were characterized and analyzed by SEM and HRTEM. Comparing to HOPG, Raman shift appears in NSOFs. The results indicate that NSOFs from cathode area have higher degree of crystallization. In addition, blue shift, E2g mode hardening 7 cm－1, may be due to its quantum dimension effect and uneven diameter distrbution.

Key words: Nano-structure onion-like fullerenes(NSOFs), Raman spectra, Blue shift
