Abstract

Microwave absorption and dielectric spectrum detection technology, with high time resolution (less than 1ns), was used for non-contact measurement of electron property in solid materials. In this paper, the photoelectron decay time-resolved spectrums of silver halide, which adsorbed the green-sensitive cyanine dyes J-aggregate, are measured by microwave absorption and dielectric spectrum detection technology. From the experiment, we find that the photoelectron decay time and the photoelectron lifetime of silver halide, which adsorbed the dye, is shorter than that of the pure silver halide; the photoelectron decay time of silver bromide is faster than the photoelectron decay time of silver chloride, the free photoelectron lifetime of silver chloride and silver bromide is 51.66ns and 13.84ns respectively; the variety extent of silver bromide is bigger than that of the silver chloride after sensitized. The effect of the dye concentration on photoelectron decay of silver halide is obvious, for silver bromide and silver chloride, the photoelectron decay become faster while the concentration increases.
