Abstract
We report the ground-state and excited-state optical absorption spectra in the visible and near infrared for several substituted fullerenes and higher fullerenes in toluene solutions. Based on these measurements, broadband predictions of the optical limiting performance of these molecules can be deduced. These predictions are then tested in the wavelength range from 532 nm to 700 nm in intensity-dependent transmission measurements. We observe optical limiting in all fullerenes measured; higher fullerenes show the greatest potential for limiting in the near infrared (650 - 1000 nm), while substituted C 60 shows optimal limiting in the visible (450 - 700 nm). We observe dramatically reduced limiting for solid forms of C 60 (thin films and C 60-doped porous glasses), indicating that efficient optical limiting in fullerenes requires true molecular solutions.
