For this purpose four samples as 0.2 mM aqueous solution of dye and solutions of dye containing 200, 300, and 400 ppm of colloidal Ag nanoparticles were prepared.All the aqueous samples showed a negative nonlinearity of the order of 10-8 cm2/W. Also it was shown that adding nano-particles decreases nonlinear refractive index of solutions. It seems that these decreases in nonlinear refractive indexeswere due to reduction of linear absorption of samples because of adding nano-particles.
