用原子力显微镜观察了阴阳离子菁染料及对应的阴离子菁染料和阳离子菁染料吸附在立方体(100)和八面体(111)溴碘化银乳剂颗粒表而形成的J-聚集体的微观结构,得到了3种不同排列的J-聚集体结构.研究结果表明,菁染料分子在溴碘化银颗粒表面不是单层吸附,而是以一定的形状聚集在溴碘化银表面.阴阳离子菁染料形成的J-聚集体为"鱼骨"状;阴离子菁染料的J-聚集体以"卡片堆积"式排列;阳离子菁染料J-聚集体为"磁砖"式结构.

In the presem 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.
