The polarization-sensitive effects of solgel materials containing various chiral media were measured experimentally. The results show that the solgel material displays optical activity when it contains organic chiral molecules and manifests depolarization when it contains inorganic chiral microcrystals with a particle size of 70 μm . Solgel material containing glass powder that also has a particle size of 70 μm displays a polarization held characteristic (i.e., the polarization of the output light is the same as that of the input light).
