Abstract

Doping with cerium (IV) oxide (CeO₂) nanoparticles can significantly enhance the thermal stability and electro-optical (EO) properties of nematic liquid crystal (NLC) systems. Thermal stability was improved without aggregation and reduction of transmittance by adding CeO₂ nanoparticles in a liquid crystal medium. In particular, the EO properties greatly improved in CeO₂-dispersed NLC cells. The threshold voltage reduced from 3.027 to 2.279 V and the response time decreased from 13.097 to 9.970 ms with increased CeO₂ nanoparticles in the NLC cells. The improved properties of liquid crystals doped with CeO₂ nanoparticles depend on the anchoring energy and the electric field of the CeO₂-dispersed liquid crystal displays.
