Linear and Nonlinear Optical Properties of Silver Nanoparticles Stabilized by Bovine Serum Albumin
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 × 10-7 esu respectively. the real and imaginary part of third order susceptibility of silver nanoparticles is found to be 1.553 × 10-7 esu and 0.7 × 10-7 esu respectively. the silver nanoparticles in BSA template show good optical limiting property.
