Present work investigated the modified aggregation behavior of a cationic oxazine dye, CRESYL VIOLET ACETATE (cas 10510-54-0) (CVA) in presence of Laponite nano clay mineral layers in aqueous clay mineral dispersion as well as in ultra thin organo-clay hybrid Langmuir Blodgett (LB) films. The presence of non-fluorescent H-dimeric sites in aqueous solution of CVA even at very low concentration diminishes its fluorescence intensity and CVA ceases to emit any fluorescence in solid state and in the ultrathin films due to the abundance of H-dimeric sites. Incorporation of clay in aqueous solution drastically modified the absorption spectrum of CVA. Organo-clay hybrid film of CVA, fabricated at higher clay concentration, showed intense J-aggregated band due to the formation of J-aggregated species. UV–vis absorption and fluorescence spectroscopy as well as in-situ Brewster angle microscopic (BAM) studies were employed in this investigation.
