%X Using spectral sensitizing technology,silver halide microcrystals can be sensitized to the visible light region.The spectral sensitizing technology is important to the modern information recording and storage,solar energy transfer and storage,and the photoelectronic devices.The photoelectron decay characteristic of silver chloride microcrystals,which is adsorbed with green sensitizing cyanine dye,is studied by microwave absorption and dielectric spectrum detection technology.The model of photoelectron decay is set up.Electron trap effect of the dye in the silver halide surface is analyzed based on the photoelectron decay model and the photoelectron decay characteristic.The results show that when the mono-molecular dye is adsorbed on the surface,shallow electron traps are created;when the J-aggregated dye is adsorbed on the surface,deep electron traps are created.The critical dose of dye that seperates the shallow electron trap and deep electron trap effects is 0.2?ml of dye(with concentration of 5.0?mg/ml)per 40?g AgCl emulsion.
