A novel dmit 2- complex: [( C 2 H 5)4 N][Co(dmit) 2], abbreviated as EtCo , was synthesized and its third-order optical nonlinearities were characterized by Z-scan technique at the wavelength of 1064 nm with laser duration of 40 ps. Z-scan curves revealed a negative nonlinear refraction at 1064 nm and a positive absorption was observed. The nonlinear refraction coefficient n2, the nonlinear absorption coefficient β and the molecular second hyperpolarizability γ have been determined to be as large as 9.51×10-19 m 2/ W , 2.19×10-12 m/W and 5.41×10-31 esu respectively, suggesting that this material has potential applications in optical limiting.

Optical limiters based on several different classes of nanomaterials are reviewed. The systems under consideration include metal and semiconductor nanoparticles and nanoscale carbon materials. For the latter, the optical limiting properties of carbon nanoparticles, fullerenes, and suspended and solubilized carbon nanotubes are summarized and compared. Mechanistic implications of the available experimental results are discussed in terms of the comparison between nonlinear scattering versus nonlinear absorption as the dominating optical limiting mechanism for different nanomaterials and for different physico-chemical states of a nanomaterial.
