Abstract
Abstract The changes of the absorption spectra by UV irradiation were measured with the optical spectrum of the J -band and the monomer band. We illustrated the topographical structure and optical structure of the merocyanine dye Langmuir–Blodgett (LB) films obtained by the scanning near-field optical/atomic force microscopy. The topographic image of the mutually mixed LB films shows more rough surface structure than expected and grains with average size of about 50 nm. In the optical transmission image, the elevated area means higher transmission than lower parts. In the continuous measurement of these dyes and the mutually mixed films, the appearance of near-field optical transmission images showed a certain dependence on the kinds of dyes with the shift and increase of transmission and the mutual mixing ratios of dyes. These experimental results suggest that there is a certain kind of interaction between these two dyes.
