Image of FIG. 1.
FIG. 1.

(Color online) Photographs showing the change in reflected color with electric field strength. These images were obtained at an oblique viewing angle using an Olympus 4040Z.

Image of FIG. 2.
FIG. 2.

(Color online) (a) Reflection spectrum of the polymer stabilized cell at different applied electric field strengths. (b) Plot of the wavelength of the reflection peak as a function of the applied electric field. The line represents a logarithmic fit to the data.

FIG. 3.

(Color online) Optical micrographs of the polymer-stabilized sample at different -field strengths of (a) , (b) , (c) , and (d) . These images were obtained using an Olympus 4040Z attached to an Olympus BH-2 microscope.

Image of FIG. 4.
FIG. 4.

(Color online) Optical micrographs of the polymer-free sample at different -field strengths of (a) , (b) , (c) , and (d) . These images were obtained using an Olympus 4040Z attached to a Olympus BH-2 microscope.

Image of FIG. 5.
FIG. 5.

(Color online) Illustration of the effect of increasing the applied electric field on the sample cell for two different scattering angles.
