Herein, we investigated the liquid crystal electro-optical response of BiTe dispersions by considering the different electric fields, concentrations, etc. The electric-field-induced birefringence was observed via the transmittance variation and macroscopic phase transition. More interestingly, the excellent solution stability allows BiTe dispersions maintain stable electro-optical response at relatively high electric filed applied (60 V/mm). As the increase of concentration, the electric-field-induced birefringence of BiTe dispersions increases significantly, reaches a maximum value (1.07 10. As short as several seconds electro-optical response time were extracted by analyzing the electro-optical response curve. This excellent electro-optical response can be leveraged to achieve electric-induced light modulation.
