Area of Science:

  • Fullerenes and Nanomaterials
  • Atomic Physics
  • Plasma Science

Background:

  • Fullerenes, such as C60, are carbon allotropes with unique cage-like structures.
  • Encapsulating atoms within fullerenes presents opportunities for novel materials and quantum applications.
  • Controlling the encapsulation of specific atoms requires advanced synthesis techniques.

Purpose of the Study:

  • To achieve the encapsulation of atomic nitrogen inside a C60 fullerene cage.
  • To confirm the successful incorporation of nitrogen atoms using spectroscopic methods.

Main Methods:

  • Utilized radiofrequency (rf) plasma to vaporize C60 molecules.
  • Introduced atomic nitrogen into the plasma environment for encapsulation.
  • Employed Electron Spin Resonance (ESR) spectroscopy for characterization.

Main Results:

  • Successfully encapsulated atomic nitrogen within the C60 fullerene cage.
  • ESR spectroscopy provided definitive confirmation of nitrogen atom presence inside C60.

Conclusions:

  • Demonstrated a viable method for endohedral fullerene synthesis with atomic nitrogen.
  • ESR is an effective technique for verifying the encapsulation of paramagnetic species like atomic nitrogen within fullerenes.
