Abstract
The nanoparticles with high-aspect ratio are oriented in the electric field more easily than normal organic molecules, because their induced dipole moments are larger than those of normal organic molecules. We measured electric field-induced birefringence of the aqueous dispersions of gold nanorods and inorganic nanosheets, and found that the inorganic nanosheet aqueous dispersions showed quadratic electro-optic effects with extremely large Kerr coefficients. On the other hand, the gold nanorod aqueous dispersions showed peculiar electrooptic effects in which their induced birefringences are proportional to the electric field intensity.
