Abstract

Photosensitivity in ferroelectric liquid crystal (FLC) material has been developed by dispersing Cadmium Sulfide (CdS) nano-particles in FLC (CdS-FLC) host. The nematic (N*) - ferroelectric (SmC*) phase transition temperature for the CdS-FLC sample in absence and presence of white light excitation decreases by 6 and 14°C, respectively, compared to host material due to enhanced disorder. The anomalous behaviour in temperature dependent dielectric permittivity of CdS-FLC sample in presence of white light excitation in N* as well as SmC* phase has been explained on the basis of enhanced free charged density and self assembly of CdS-LC in the phases.
