Abstract
Photosensitive thiacarbocyanine dye adsorbed on practical photographic emulsion AgBr microcrystals has been visualized by ultra-low energy scanning electron microscopy at room temperature. The dye is observed in stripes along the [210] and/or [120] direction on the AgBr (001) surface, which indicates that the dye molecules nucleate and grow with a certain epitaxial relation in respect with the AgBr lattice. The stripes become to a patch with increasing surface coverage. Using atomic force microscopy the stripes or patches are found to be not always monolayer. It is concluded by taking account of results of analytical color fluorescence electron microscopy that they are constructed with photoelectrically separated J-aggregate particles.
