Spectroscopic Study of Liquid Crystal doped with Nano - Powder

Suspensions of ferroelectric nanoparticles in acholesteric liquid crystal host possess enhanced anisotropy and are sensitive to an applied electric field. Here we also show that the particles contribute to the total achievable phase shift of the composite material.The textures and Phase transition Temperatures have been studied by Polarizing Optical Microscopy (POM) and Differential Scanning Calorimetry (DSC).The absorption of sample in visible range were found by Ultraviolet – Visible (UV) Spectroscopy. These results may be used to design new materials for displays.
