Optical investigation on g-Fe2O3 nanoparticles doped silica gel matrix for the realization of birefringent components

Résumé

We present an optical study of silica gel matrix doped with maghemite /spl gamma/-Fe/sub 2/O/sub 3/ nanoparticles originating from a ferrofluid. This work is a preliminary study for building adjusted birefringent components suitable for ellipsometry. Silica gel matrix is obtained as sol-gel synthesis. Results show that pure and doped samples solidified out of a magnetic field are quasi-isotropic, whereas samples solidified in the presence of a magnetic field exhibit a very large permanent linear birefringence comparable to that produced by the ferrofluid under the same magnetic field.
