摘要
The morphologies of deposited C-60 on a copper substrate from a C-60-benzene solution were evaluated by using Scanning Electron Microscopy. It was found that the forms of deposited C-60 were dependent on the aggregation of C-60 in its original solution. During natural vaporization of benzene solution on a copper substrate, independent C-60 molecules in the solution assembled into crystal C-60 on the substrate, whereas the aggregates of C-60 in the solution were remained as amorphous C-60 particles on the substrate. However, if spinning was employed during vaporizing solvent, the C-60 aggregates were destroyed, leading to the formation of crystal C-60. Furthermore, the speed of spinning a substrate can tune the size and shape of deposited C-60.
