Abstract
Change in morphology of merocyanine - Cd aracbidate mixed Langmuir-Blodgett (LB) films has been studied before and after the hydrothermal treatments (HTT) of 100% humidity at temperatures ranging from 30oC to 90oC using a polarized light photomicroscope. By applying HTT, the J-band with an in-plane anisotropy in the as-deposited LB films is reorganized into an isotropic phase characterized with a narrowing of the peak Correspondingly, the microscopic image, initially anisotropic and featureless under polarized light, changes to be isotropic and filled with round-shaped domains as large as 0.1 mm or more in diameter. Observation of four types of LB samples with different monolayer stacks indicates that each domain is confined to one single monolayer.
