Self-Assembling Hybrid Nanoparticles During Simultaneous Deposition of Co and C60 on Sapphire

Popis výsledku v původním jazyce

The Co-C60 nano-composite film prepared by simultaneous deposition of Co and C60 at room temperature (RT) on sapphire with high content of cobalt (50 at.% Co) is recognized as ensemble of the fcc-Co nanocrystals (5-6 nm in size) separated by the C60-based matrix. The phase separation causes the phenomena sufficiently influencing the nano-composite structure. One of them is retaining the Co atoms within the C60-based matrix that occurs during the separation process. Analysis of the Raman spectrum arguesthat the retained Co atoms compose the Co-C60 polymers. Another phenomenon is the structure relaxation releasing the internal stress. Raman spectra show decrease of the Co-C60 polymerization efficiency if deposition temperature increases from RT to 200 °C. This is caused by decreasing amount of the retained Co atoms in matrix due to more complete phase separation.
