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.

AbstractWe report an investigation into the mechanism responsible for the optical limiting behavior in multiwalled carbon nanotubes. We conducted energy-dependent transmission measurements, picosecond time-resolved pump-probe, and nonlinear scattering experiments at 532-nm wavelength on multiwalled carbon nanotube suspension. For comparison, C60-toluene solution and carbon black suspension were also studied in the same experiments. The similarities that we observed between the multiwalled carbon nanotubes and carbon black suspension suggest that nonlinear scattering, which is known to be responsible for the limiting action in carbon black suspension, should play an important role in the limiting effect in multiwalled carbon nanotubes.

Pulsed photoacoustic studies in solution of C 60 in toluene have been made using the 532 nm radiation from a frequency doubled Nd:YAG laser. Though C 60 is found to exhibit the phenomenon of optical limiting, the results on photoacoustic measurements do not give any indication of multiphoton transitions as suggested in some of the earlier works. Results of photoacoustic measurements show that excited state absorption is the dominant process responsible for optical limiting while phenomena like nonlinear scattering may contribute to a lesser extent.

Limiting Threshold

In order to determine the origin of optical limiting in singlewall carbon nanotube (SWNT) suspensions, we carried out Z-scan and pump-probe experiments at 532 nm and 1064 nm, for different input energies. We evidenced strong nonlinear scattering due to heat transfer from the carbon nanotubes to solvent which induced solvent bubble growth and a nonlinear refractive effect. We noticed similar comportment at 1064 nm and at 532 nm, but with a lower bubble growth threshold at 532 nm. At the microsecond timescale, we evidenced cavitation bubbles. We also evidenced, via emission studies, a phase change corresponding to optical limiting threshold, which we associated to carbon nanotube sublimation. Optical limiting performances of water and chloroform suspensions were compared and solvent effects are discussed.
