Solvent-dependent optical limiting response of platinum nanoparticles stabilized by 60 fullerene derivative

摘要

The optical limiting performance of platinum nanoparticle protected by C60 derivative in chloroform, ethanol and dimethylformamide (DMF) was measured with 532nm, 8ns duration laser pulses. Experiments showed that the optical limiting is solvent-dependent. The origins and solvent effect of the optical limiting were analyzed. It was proposed that the absorption-induced scattering is the main mechanism causing the optical limiting behavior and solvent effect.
