Abstract :
The third-order nonlinear optical response of the water-soluble inclusion complex consisting of C60 incorporated in γ-cyclodextrin was examined employing the z-scan technique. Using 532 nm, 10 ns laser pulses, significant optical limiting action was observed, the effect being slightly lower than that of pure C60 diluted in toluene. Ageing of the C60/γ-cyclodextrin–water solution results in the formation of aggregates that enhance the optical limiting action by a factor of almost two.
