Photolysis properties of merocyanine dye LB films by various time of UV irradiation.

We fabricated the merocyanine dye LB films with arachidic acid (MD LB films). We compared absorption peak of before and after added Cd2+. The optical absorption peak of the MD LB films was shifted to 610 nm at 535 nm, when Cd2+ ions were added. We also investigated the optical absorption peak of the LB films by various time at 365 nm UV. We confirmed J-aggregation and photolysis properties. This is that studied the application possibility of the switching device and the nonvolatile memory.
