Abstract
We have synthesized highly stable silver nanoparticles in aqueous solution at room temperature by standard reduction method using bovine serum albumin (BSA) as a stabilizing agent. The nonlinear optical properties of nanoparticles were investigated using Z-scan technique at 532 nm. The obtained nonlinear absorption coefficient and negative nonlinear refractive index is found to be 88.36 cm/GW and -5.1 × 10-7esu respectively. The real and imaginary part of third order susceptibility of silver nanoparticles is found to be 1.553 × 10-7esu and 0.7 × 10-7esu respectively. The silver nanoparticles in BSA template show good optical limiting property.
