In a cyanine dye LB film, the J-aggregates of the dye molecules form domain
structure. The shape and size of this structure are largely influenced by
the conditions of film fabrication. We made a through investigation about t
he effects of counter anions of the dye molecules and ions as additives in
the subphase on the domain structure in dye monolayers at the air/water int
erfaces and in LB films by using a fluorescence microscope. We found the co
nditions under which we can promote or prevent the growth of the domains, a
nd discussed the influence of anions on pi-A isotherm.
