Abstract

This paper reports on the enhancement of optical nonlinearity α-Fe₂O₃ nanoparticles on decorating with copper nanoparticles. Undecorated as well as copper nanoparticles decorated iron oxide nanoparticles are synthesized by a solvothermal method and characterized by SEM, XRD. The nonlinear optical response is characterized using the open Z-scan experiment. Analysis of the results indicates two photon absorption followed by saturable absorption to be the predominant mechanism of optical nonlinearity. The two photon absorption coefficient in the copper nanoparticles decorated Fe₂O₃ nanoparticles is found to be larger in comparison with that of the undecorated Fe₂O₃ nanoparticles.
