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