摘要：

Nonlinear optical properties of extracted higher fullerenes - C-70, C-76, C-78; and C-84 - are theoretically investigated. Magnitudes of off-resonant third-harmonic generation are calculated using the intermediate exciton theory. We find that optical nonlinearities of higher fullerenes are a few times larger than those of C-60. The magnitudes of nonlinearity tend to increase as the optical gap decreases in higher fullerenes.
