Research Abstract |
When gold nanoparticles (NPs) were doped in a cholesteric blue phase (BP) liquid crystal (LC), the temperature range of the BP increased from 0.5 to 5 oC. We believe that the NPs accumulate in the lattice disclinations of BP LC, stabilizing the overall BP structure. Using the NP-stabilized BP LC, polarization-independent refractive index (RI) modulation can be achieved by applying an electric field parallel to the direction of light transmission. We show that field-induced BP-cholesteric transition is suppressed and a larger RI tuning can be achieved.
