The diffferent changes of relative intensity and depolarization ratio （p = I/I） of Raman bands of C 6 0 films on different substrates were observed. Some new Raman bands were also observed in SERS spetrum of C 6 0 These results could be explained by the interactions between C 6 0 and surface of substrates. The results suggested that the spherical fullerene C 6 0 molecule with I h symmetry could be used as a probe to investigate the adsorbate-surface interactions. 拉曼光谱 C60膜 表面增强拉曼光谱 Raman spectroscopy fullerene-C60 film surface-enhanced O657.312 1992-03-01 2021-04-01 3
