The influence of green-sensitive cyanine dye adsorption on the surface structure of cubic AgCl micro-crystal

The photoelectron decay characteristic of AgCl micro-crystal, which adsorbed with the green-sensitive cyanine dye, has been obtained by using the microwave absorption and phase-sensitive measurement technique. It is found that when the sensitive concentration is more than 0.2 ml (5.0 mg/ml)/40 g emulsion, the dye J-aggregate is formed on the surface of silver chloride micro-crystals, the free photoelectron of silver chloride decay become faster than the pure silver chloride, it is showed that the Ag_i ⁺ of AgCl micro-crystal surface is increased .
