| Popis: | The influence of thermal annealing in the air at the temperatures of 393, 453 and 473 K on the morphological and crystalline structure of fullerene C 60 films was investigated using the X-ray, electron-diffraction and electron-microscopic methods, and also the Raman spectroscopy. It is established that the annealing of C 60 films leads to the orientation of grains of the fcc phase by plane (110) in parallel to the substrate, the considerable increase of the fcc lattice parameter, the decrease of the hdp phase content and the deformation (change in the form) of C 60 molecules, which is confirmed by an increase in the intensity of vibrations 1399 and 1425 cm −1 and by the appearance of new bands 934, 1592 and 1685 cm −1 in the Raman spectra. |
