dc.description.abstract-enSingle crystal and polycrystal of fullerene C60 have been grown by sublimation in a fused silica ampoule. Spectro-ellipsometric data from the polished surface of the polycrystal are different from the ones of the single crystal. This difference can be attributed to the existence of grain boundaries and voids associated with polycrystals, and has been explained using the Bruggeman Effective-Medium-Approximation (EMA). In helium, argon, hydrogen, or nitrogen atmosphere, the polycrystal has shown reversible change in spectra with pressures. This change has been able to be interpreted by a physisorption model in which gas molecules enter the voids and are occluded as a quasi-liquid. For oxygen atmosphere, the spectrum has shown complicated and irreversible change, implying that some part of oxygen atoms remains in the voids due to possible chemisorption.en
