Abstract
The dielectric, electro - optical (E - O) and thermo dynamical behaviour of ZnS quantum dot (QDs) dispersed ferroelectric liquid crystal (FLC) material has been studied. Change in SmC*- SmA phase transition temperature has been observed. Width of SmC* phase is found to be slightly increased after the dispersion of ZnS QDs, which has been confirmed by the dielectric and E - O study of composites. A significant modification in the FLC material parameters (like spontaneous polarization, optical response time, tilt angle and rotational viscosity) after the dispersion of QDs has been observed. Significant fastening of the optical response time for low conc. of QDs dispersed FLC composite shows its utilization in advanced display devices.
