Abstract

We present our results on the linear and nonlinear optical properties of cobalt nanoparticles synthesized by laser ablation in different organic solvents. Transmission electron microscopy and UV-visible absorption were used for the characterization of morphology, size distribution, and optical properties, respectively. Nonlinear scattering and nonlinear absorption are regarded as the processes contributing to the observed optical-limiting behavior in these nanoparticles, which were investigated by performing Z-scan measurements. Due to strong two-photon absorption and nonlinear scattering, cobalt nanoparticles dispersed in chlorobenzene and chloroform exhibit superior optical-limiting threshold when compared with other solvents.
