摘要：

Photoluminescence spectra of C-60 crystals with high quality was measured before and after the mechanical deformation. New peak at 685 nm appeared after the deformation. The peak was observed only at temperatures lower than about 90 K, where its intensity decreases with increasing temperature. The temperature dependence of the peak intensity was correlated with that of main other peak at 735 nm, which would originates in intrinsic C-60 crystals. From these results, the origin of the peak at 685 nm is discussed in the light of crystal defects, especially dislocations.
