Study of optical switching characterstics in nano doped liquid crystal

Abstract

Nano doped Liquid Crystals are thermo tropic exhibiting various phase transitions under the influence of electric field. The molecules behave differently at each phase. The parameters like refractive index, optical polarization, dielectric constant, switching times and other physical parameters are different in different Liquid Crystal Phases. For the purpose of studying the electro-optic properties of Liquid Crystals, a specially fabricated surface stabilized glass cell was imported from USA with 5 micrometers separation. One of the critical components for studying the electro-optic properties of liquid crystals is the sample cell. The electro-optic switching properties of 8OBA-n and 9OBA-n are studied for signals of frequencies from 30 Hz to 2 MHz.
