Cd1−X ZnXS/ZnS core/shell quantum dots in nematic liquid crystals to improve material parameter for better performance of liquid crystal based devices

The present study is devoted to characterize the dielectric and electro optical parameters of the nematic liquid crystal NLC 2020 and core/shell quantum dots (CSQD) + NLC composite system with dielectric properties being considered in both planar and homeotropic standpoint. The investigation shows enhancement in the performance of NLC by dispersing small (0.1 wt%) concentrations of (CSQD). Estimation of total power loss (TPL), specific power loss (SPL) along with high figure-of-merit (FoM) and faster electro- optical response are the promising results of this investigation. Parameters like response time, rotational viscosity, viscoelastic coefficient has been changed substantially for different composite system (0.1 wt% and 0.25 wt% conc.). Total power loss (TPL) and Specific power loss (SPL) have been analyzed in the present study. The investigation reveals that smaller concentration (0.1 wt%) gives better results as compared to 0.25 wt%. The motive of the present investigation is to evaluate TPL, SPL and to improve material parameter figure-of-merit for better performance of NLC based devices.
