“…The resulting potential is presented in Figure 1, where we show the cross-section passing through the center of the fullerene and the carbon atom and the section through the center of the fullerene and the center of the segment connecting two adjacent 2 Journal of Nanomaterials carbon atoms. Similar to the findings of our previous works [7,12], we observe that the value of the potential in the center is lower for the charged C 60 +2 than for the neutral fullerene. For the energies above the potential value at the center of the fullerene, we find both the well-studied surfacelocalized electron states (SLES) and volume-localized electron states (VLES).…”

“…( Figure 4(a)), and for comparison, the cross-sections for the C 60 +5 fullerene are presented (Figure 4(b)) (see [12]). On the basis of the numeric data for wave functions, one can evaluate the dipole moments and the lifetimes of the quantum transitions between VLES and SLES and between SLES and SLES.…”

We study the spontaneous emission processes for the quantum transitions between electron states of a charged C60 fullerene. Lifetimes for the transitions between the volume-localized electron levels and the surface-localized electron levels are evaluated and compared with the transitions between two surface-localized electron levels. We find the lifetimes by computing the transition dipole moments on the basis of the numeric calculations of the three-dimensional electron wave functions of a charged fullerene by making use of the density functional theory method implemented in the QuantumEspresso package. We show that the lifetime of a volume-localized level is of order of 1 μs for a transition energy of about 5 eV. This suggests to consider the possibility of using charged fullerenes for generating short-wavelength radiation, including coherent radiation in this range.
