PHOTOINDUCED GYROTROPY OF POLARIZATION-SENSITIVE LUMINESCENT HOLOGRAM MATERIALS BASED ON AQUEOUS MEDIA

Abstract

The photoinduced gyrotropy (nonlinear optical activity) of polarization-sensitive luminescent recording materials based on various drinking and mineral waters are herein studied by the methods of polarizationluminescent holography. Photoluminescence spectra and spectra of the degree of circularity of (circular)polarization luminescence of the reconstructed phantom object are obtained. It is shown that during the transition between the racemic to chirally pure phases, a significant modification of the spectra of dynamic multiplex luminescent Denisyuk holograms is observed in the medium, in particular, a polarizationholographic memory of the gyrotropic properties is expressed in the considered water media. The polarization-holographic analysis of the optical polarization spectra of aqueous media makes it possible to obtain additional information about anisotropic-gyrotropic holographic materials, namely, the intrinsic chirality of the components of each compound present in the medium.
