A theoretical and experimental study on optical limiting in platinum nanoparticles

Optical limiting performance of PVP-stabilized platinum nanoparticles in methanol is investigated with 8 ns pulses at 532 nm. The experimental results show that the platinum nanoparticles possess strong optical limiting effect. We propose a theoretical model based on Mie extinction theory to describe nonlinear optical limiting (OL) behavior of metal nanoparticles. The theoretical analysis and experimental results show that the main mechanism for OL of platinum nanoparticles can be attributed to interband transition of platinum during the excitation of nanosecond pulses.
