摘　　要：We observed morphological modification of rod-shaped C60 solvate crystals using a facile hydrothermal method.The initial C60 rods were changed from smooth rods to rough rods,porous rods or pieces under different hydrothermal conditions.During the hydrothermal treatment,the initial samples underwent a decomposition-recrystallization process,which can be tuned by the content of alcohol in the hydrothermal solution,thereby leading to modification of the morphological properties of the initial C60 rods.In addition,the rough and porous C60 rods prepared in our work exhibit excellent photoluminescence intensities that are approximately 7 and 3 times higher than those of pure C60 powders,respectively.Our results suggest that the hydrothermal method is a potential route for fabricating fullerene materials with controllable morphologies and novel functions.
