Paper Abstract

The effect of light on the hardness of C60 crystals was investigated. The hardness increased with the development of illumination time, and then reached a constant value. The hardening phenomenon was clearly observed at temperatures lower than about 390 K. In addition, it was shown that the red light with the wavelength of about 700 nm leads to the maximum effect for the hardening. The origin of the hardening is discussed in the light of the photo-induced polymerization of C60 molecules in the crystals.
