Abstract:
An anodic aluminum oxide (AAO) template is prepared by anodizing aluminum in oxalic acid solution. C60 crystals were grown, using the pressure difference method, in the pores of the template, representing a brushlike thin film layer with a honeycomb boundary structure in one side and nail arrays in the other side. Different Raman spectra of the C60 thin film from the both sides are presented, which indicate the different uniformly ordered structure character and the interface behavior of the C60 film on the surface with C60 crystals in the AAO nanopores. On the basis of energy and group theory, the strengthening of the Raman intensity and the broadening of Raman modes may imply that more transition spectral lines between vibration or rotation energy levels of C60 molecules were excited and detected.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
