Abstract
Present communication reports the micellar effect on the increased fluorescence efficiency of a fluorescent dye in the complex LB film. In the complex Langmuir monolayer and Langmuir-Blodgett films, anionic Xanthene dye molecules organized differently when the films were prepared below and above the critical micellar concentration (CMC) of Cetyltrimethylammonium Bromide (CTAB) in the mixed solution of the Langmuir Trough. In-situ Brewster Angle Microscopic (BAM) studies showed the visual images of the Langmuir monolayers during the formation of the films. UV–Vis absorption and Fluorescence Spectroscopic studies were employed to study the spectral characteristics of the complex films.
