Paper Abstract

The photoelectron decay characteristic of AgCl mircrocrystals, which are adsorbed with the green-sensitive cyanine dye, has been obtained by using microwave absorption and phase-sensitive measurement technique. Combined with the absorption spectra of cubic AgCl emulsion sensitized by green-sensitive cyanine dye, the influence of green-sensitive cyanine dye adsorption at various adsorbing concentration on the surface structure of cubic AgCl microcrystals is investigated. It is found that when the concentration is less than 0.02ml(5.0mg/ml)/40g emulsion, the dye J-aggregate is not formed on the surface of silver chloride microcrystals, the surface of AgCl is decorated by the dye, the dye takes place shallow electron trap effect; when the sensitive concentration is more than 0.2ml (5.0mg/ml)/40g emulsion, the dye J-aggregate is formed on the surface of silver chloride microcrystals, the Agi+ of AgCl microcrystal surface is increased, the dye takes place the deep electron trap effect
