Blue Phase Liquid Crystal Nanocomposites and Devices
We have demonstrated that blue phase (BP) liquid crystals (LC) are stabilized as a result of doping gold nanorods (AuNR) and can enable fast-switching devices. Temperature range studies were conducted with imaging through a polarized optical microscope (POM). The BP temperature range was increased with increasing concentration of nanoparticles in the BP mixture. The optimization in the doped BPLC device also leads to a reduction in threshold voltage and turn on voltage in addition to its intrinsic property of sub-millisecond response time in the field-induced optical Kerr effect.
- Electrically-driven liquid crystal spatial light modulators, active optical elements and displays
- Fast switching time
- Lower applied voltage than pure BPLC
