Optical limiting of platinum nanoparticle stabilized by C60 derivative

The optical limiting performance of platinum nanoparticle protected by C₆₀ derivative was investigated by using 8-ns laser pulses at a wavelength of 532nm. The investigation indicated the sample could provide enhanced optical limiting even better than benchmark optical limiting material, fullerene C₆₀ dissolved in toluene. The origins of the strong optical limiting were discussed based on reverse saturable absorption and nonlinear scattering.
