Enhanced photorefractivity from ion-doped polymer-dispersed liquid crystals
Article Abstract:
Dynamic near-field scanning optical microscopy (NSOM) and asymmetric two-beam coupling experiments are performed on thin films of photorefractive polymer-dispersed liquid crystals (PDLCs). Results obtained from films doped with perylene and naphthalene diimide are compared to those obtained from films that have also been doped with tetrabutylammonium tetrafluroborate.

Simultaneous near-field optical birefringence and fluorescence contrast applied to the study of dye-doped polymer-dispersed liquid crystals
Article Abstract:
A demonstration on a near-field optical method for simultaneously obtaining birefringence and fluorescence contrast from dye-doped polymer-dispersed liquid crystal (PDLC) films is presented. The results viewed that the field dependence of dye-reorientation varies spatially across individual droplets and in most cases parallels reorientation of the liquid crystal.

Exploring and photorefractive effect in polymer-dispersed liquid crystals using near-field scanning optical microscopy
Article Abstract:
Static and dynamic near-field scanning optical microscopy (NSOM) methods and computer simulations are used to understand the dynamical phenomena associated with photorefractivity in dye-doped PDLC thin films. The dynamics observed become more uniform and less sensitive to interfacial phenomena than in the absence of ions.
