Abstract

Optical limiting has been investigated for higher fullerenes and compared with C60. The transmission through an aperture placed after solutions of C76 C78 and C84 in tetrahydronaphthalene was measured using Q-switched laser pulses with a wavelength of 532nm and a pulse width of 8ns FWHM. Unlike C60 the transmission for these higher fullerene solutions decreased linearly with increasing optical pulse energy. We attribute the linearized optical limiting response to self-defocusing of the optical beam and the absence of excited-state absorption. The ground state absorption spectra for the higher fullerenes suggest their use for optical limiting in the near infrared and the C84-tetrahydronaphthalene solution was found to be an optical limiter at 1.064μm.
