摘要：

We have observed enhanced optical limiting behavior in solutions of a derivatized fullerene (phenyl-C-61-butyric acid cholesteryl ester) from 532 to 700 nm. Transient absorption measurements determined the spectral and temporal regions of interest for optical limiting in C-60 and in C-60 derivatives that are due to a reverse saturable absorption mechanism and predicted enhanced limiting at longer wavelengths. Intensity-dependent transmission measurements made at several wavelengths confirmed these results. The increased solubility and the broadened ground-state absorption of the functionalized C-60 make it suitable for use as an optical limiter in the red and the near infrared.
