二色性蛍光色素を用いた液晶ブルー相格子中の配向ベクトルの共焦点顕微鏡観察

抄録

The structure of liquid crystal blue phases doped with dichroic dyes was observed by confocal laser scanning microscope using polarizing excitation light with controllable polarization plane. Depending on the polarization plane, different patterns with periods of sub-micrometer were observed. The spatial periods in the images at fluorescent mode using dichroic dye were found to be half of those in images at conventional reflection mode. It is expected that the contrast of light and shade in the fluorescence images reflects distribution of direction of the directors in the blue phase lattice.
