Orientation control of dye molecules in a liquid crystal.
Laser dye molecules (coumarin 6) were dissolved in a nematic liquid crystal MBBA + BBCA. Great changes in polarization and fluorescence vs applied voltage were found as well as a change in dielectric constant. Molecular orientation of the liquid crystal under the electric field and association of the dye molecules are identified as having the greatest effect on the fluorescence intensity.
