Abstract
The third-order optical nonlinearity of Fe2O3 nanoparticles capped with glutamic acid molecules and bare particles in hydrosol have been investigated by Z-scan technique. The signs and magnitudes of nonlinear refractive coefficients (γ) of these two kinds Fe2O3 nanoparticles were obtained. The results suggested that γ was intensively subject to the surface-capping molecules. This phenomenon may be in particular considered with local field enhancement effect related to the refractive index of the media around nanoparticles, and the local field enhancement factor was evaluated by the solution of Laplace's equation.
