title: [The absorption spectrum of green-sensitive cyanine dyes J-aggregate adsorbed on silver chloride microcrystals].
abstract: The silver chloride microcrystals emulsion which are sensitized by the adsorbed green-sensitive cyanine dye of different concentration, was studied by using the absorption spectrum. The experiments show that when the sensitizing concentration is less than 0.02 mL (5.0 mg x mL(-1))/40 g emulsion, the dye J-aggregate is not formed on the surface of silver chloride microcrystals; when the dye concentration is more than 0.2 mL (5.0 mg x mL(-1)/40 g emulsion, the dye J-aggregate is formed on the surface of silver chloride microcrystals; compare to the M-state of dye, the maximal absorption peak of J-aggregate shifted to a longer wavelength by about 50 nm. It was found, when the J-aggregate is formed, the absorption in the wavelength range of more than 450 nm is increased.
