| Abstract: | Two novel nanocomposites based on fullerene C 60 structured systems with gold nanoparticles were investigated with 532nm, 8ns duration laser pulses. The comparison between Z-scan experimental results and theoretical analysis indicates that the nonlinear absorption primarily depends on the ligands, and the nonlinear refraction comes mainly from the contribution of gold nanoparticles in the materials. The comparison of the two nanocomposites with the well known C 60 toluene solution in optical limiting properties was performed. The optical limiting mechanisms were discussed |
