Photosensitive Dye J-Aggregates Form in Monolayer Adsorption or Multilayer Growth on Gelatin-Grown Silver Halide Emulsion Microcrystals?

摘要

To elucidate the problem,which has not been solved,on the morphological structure of photosensitive dyes adsorbed on gelatin-grown silver halide emulsion microcrystals,our previous investigations are reviewed.The investigations were systematically performed using environmental scanning electron microscopy(ESEM),cathodoluminescence scanning electron microscopy(CL-SEM),low-voltage high-resolution scanning electron microscopy(LV-HRSEM)and atomic-force microscopy(AFM),and revealed the multilayer growth of the J-aggregate dyes.The other investigations that supported the monolayer adsorption are commented with criticism.
