By using fluence-dependent transmission measurement with nanosecond laser pulses, we have studied optical limiting (OL) properties of new carbon nanocomposites as well as amorphous Si x N y or amorphous SiC coated carbon nanotubes suspended in distilled water. The observed nonlinearity at 532 nm contributed to OL performance of the carbon nanocomposites or carbon nanoballs (CNBs) is suggested to have its origin in the optically induced heating or scattering effects. It is found that when the linear transmittance of the CNBs is less than or equal to 70%, the intensity-dependent transmission of the CNBs is comparable to that of C 60. While at 80% linear transmittance, CNBs possess better OL behavior than that of C 60. These findings strongly support a potential application of CNBs for all laser protection devices. We have also observed OL effects in the amorphous silicon nitride ( a - Si x N y) and amorphous silicon carbide ( a - SiC ) coated multi-walled carbon nanotubes (MWNTs) at wavelengths of 532 and 1064 nm, and found that their OL performances are slightly poorer than that of their parent MWNTs. The possible sources of thickness-dependent OL effects of a - Si x N y and a - SiC coated MWNTs are discussed.

The stability of the carbon nanotubes suspension is poor, resulting from the characteristic of insoluble in aqueous solution. Nevertheless, optical limiting devices need long-term stability. In the interest of finding effective and stable materials for optical limiting, we had tried to combine the multi-walled carbon nanotubes (CNTs) and ionic liquids surfactant (hydroxypropyl sulfo imidazoline) to obtain a new dispersion. Ultimately, we achieved non-covalent modification to carbon nanotubes. The electronic structure of the carbon nanotubes’ surface was protected integrality and the dispersion was stable and effective. It was verified by experimental observation through a field scanning electron microscopy (SEM). Finally we did a series of experiments to studied the optical limiting characteristics of the new dispersion. The results manifested that the dispersion system owned well optical limiting properties and better stability, at the same time, we also proved that the negative pressure environment could also do well to optical limiting effect.
