Outline of the experimental apparatuses. (a) Supercritical fluid chamber. Crystals composed of C60 molecules are placed on a silicon plate set at the bottom of the chamber. The chamber is then filled with carbon dioxide of critical density. The temperature is set at 36.0°C by a heater regulated by a PID controller. Crystals composed of C60 molecules are left in the chamber for 24 h. Clusters formed by C60 molecules are observed by an SEM. (b) UV light irradiation chamber. The clusters formed by C60 molecules are placed in the chamber which is filled with air at 1 atm. After irradiation of UV light for 3 h, the clusters are observed by an SEM and mass spectroscopic analysis is carried out.
