Abstract
In this study, we fabricated the optical system of merocyanine dye (MD) using the Langmuir-Blodgett (LB) method with various mixing ratios and numbers of layers to control its optical characteristics. We used quartz crystal microbalance (QCM) measurements and UV-visible spectroscopy to monitor and analyze the adsorption process of MD LB film. Aggregates, J form, were detected in MD LB film by UV-visible spectroscopy. The thermal relaxation kinetics for MD LB film was also investigated using UV-visible spectroscopy and the QCM. The thermal relaxation of MD LB film affected the vibration model of QCM and produced a resonant frequency shift. This strongly suggests that QCM technology has potential application in understanding the optical processing of MD LB films.
