چکیده انگلیسی
Metal-fullerene nanocomposite thin films with low concentration of Cu metal embedded in fullerene matrix have been synthesized using thermal co-deposition method. An ion irradiation with 120Â MeV Ag ions beam was performed to assess the radiation effects for Cu (3%)-C60 nanocomposites at different fluences 1Â ÃÂ 1012, 6Â ÃÂ 1012, 1Â ÃÂ 1013 and 3Â ÃÂ 1013 ions/cm2. Optical properties and surface morphology of nanocomposite thin films were studied using UV-visible spectroscopy and atomic force microscopy, respectively. Absorption spectra demonstrated that absorption intensity of nanocomposite thin film was increased and modes of fullerene were diminished with fluence. The thickness of the film and atomic metal fraction in matrix were estimated by Rutherford backscattering spectroscopy and found to be â¼45Â nm and 3%, respectively. Transmission electron microscopy was performed for structural and particle size evaluation of Cu nanoparticles (NPs) in matrix at higher fluence. Structural evolution of copper-fullerene C60 nanocomposite thin films with increasing fluence of 120Â MeV Ag ion beam was studied by Raman Spectroscopy, which confirmed the amorphization of matrix (fullerene C60) at higher fluence.
