Electric field-induced uniaxial orientation of polarization splay modulated (B7) liquid crystal phase |
초록 |
To generate large optical texture, we have utilized chemically modifying substrates using self-assembled monolayers (SAM) having molecule-phobic characteristic. A droplet on the substrate treated by SAM exhibited large focal conic domains. And an in-plane electric field spread out droplet that finally changed to uniform thin film. The liquid crystalline molecules in the film exhibited uniaxial orientation in the same direction of the electric field, resulting in linearly polarized light emission due to fluorescence of the molecules. The highly aligned B7 film with large area was characterized by depolarized transmitted light microscopy (DTLM) and fluorescence polarizing microscopy (FPM). And the B7 film will provide great opto-electronic applications such as a linearly polarized light emission film and a fast light modulator. |
