Abstract:

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.
