Abstract：In the present paper, the J-aggregate structures of three types of cyanine dyes adsorbed both on 0.4 μm AgBrI cubic crystal surface (100) and on 1.8 μm AgBrI tabular crystal surface (111) were studied by use of atomic force microscope (AFM). Several types of aggregation structures were observed for the three types of dyes on AgBrI crystals. Rectangular structure was formed on the crystal faces of (100) and (111) for both anionic and cationic cyanine dyes. On the surface of anionic-cationic cyanine dyes, however, herringbone stacking structure was formed, and a banded spectrum was correspondingly detected on the AgBrI crystal surface.
