Abstract Photoelectrons plays an important role in the latent image formation process of silver halide materials, and the decay characteristic of photoelectrons are dependent on the structure of silver halide microcrystals to a great eｘtent. In this paper, the decay spectra of free photoelectrons and shallow-trapped electrons were obtained bｙ optics and microwave doｕble resonance technoloｇｙ． The depth and density of electron traps in silver halide microcrystals were discussed. Moreover，ｕsinｇ the lifetime of free photoelectrons, the optimal doping amount of shallow electron trap dopants was found bｙ analｙｚinｇ the distribｕtion condition of electron traps in silver halide.
