摘要：
It is well known that the physical and electro-optical properties of liquid crystals can be controlled by doping with nanoparticles. In this study, we investigated the electro-optical properties of homogeneous aligned liquid crystal devices doped with various titanate nanoparticles, such as TiSiO4, BaTiO3, SrTiO3 and mixtures of BaTiO3 and SrTiO3. Doping liquid crystals with titanate nanoparticles decreased the threshold voltages of the liquid crystal mixture cells. In particular, the liquid crystal cells doped with SrTiO3 nanoparticles exhibited the lowest switching amplitude of 0.643 V. The high performance of the liquid crystal cells doped with various titanate nanoparticles indicates that the proposed liquid crystal devices have strong potential for use in materials for advanced liquid crystal displays.
