Investigation of C60 and C70 fullerenes under low energy ion impact

Gamma irradiation induced surface plasmon resonance of Cu nanoparticles in fullerene C60

“…This again confirms that gamma irradiation does not affect the structure of fullerene C 60 molecule, and therefore, it is preferred over high‐energy charge particle irradiation. Whereas, at high doses, fullerene molecule is also destroyed and converted into amorphous carbon 7–9,19 …”

“…Thermal annealing and Gamma irradiation are some of other techniques to tailor the properties of the target material with minimum damage to the material. 7,8 The difference between ion irradiation and gamma irradiation is the source of irradiation; for ion irradiation, one uses the charge particle accelerators and for gamma irradiation, Co-60/Cs137 is being used. On one hand, gamma rays are sparsely ionizing due to low linear energy transfer (LET) radiation; on the other hand, ion beams are densely ionizing (high LET radiation).…”

“…Our group has been working on various ion irradiation and thermal annealing studies of fullerene and fullerene-based nanocomposites such as Ag C 60 , Ag C 70 , Au C 60 , and Au C 70 for various applications such as in organic solar cells and surface plasmon resonance (SPR)-based sensors. [7][8][9] The study of fullerene and its derivatives are now the field of interest not only because of its various applications in the practical world such as optical limiters, biosensors, energy storage devices, nuclear reactors, and organic solar cells [10][11][12][13][14][15] but also because it is found in the interstellar medium. 16 The incorporation of Ag and Au metal nanoparticles in the fullerene matrix can enhance the light trapping efficiency, and therefore, these nanocomposite materials are best suited for organic solar cells.…”

“…The degree of amorphization depends on the ion dose and beam parameters. Thermal annealing and Gamma irradiation are some of other techniques to tailor the properties of the target material with minimum damage to the material 7,8 …”
