摘要
Metal nanoparticles synthesized by 200 keV Ag ions into silica with dose of 2 x 10(17) ions/cm(2) has been studied. Third-order nonlinear optical properties of the nanoparticles were measured at 1064 nm excitations using the Z-scan technique. Results of the investigation of nonlinear refraction by the single beam Z-scan configuration are presented and the mechanisms responsible for the nonlinear response were discussed. Curve fitting analysis, based on MATLAB features for Ag nanoparticle optical limiting experiment, is used. The results show that Ag nanoparticles display a refractive optical limiting effect at 1064 nm. Published by Elsevier B.V.
