【Abstract】 The detecting apparatus of the photon acting on the silver halide dielectric material is set up in this paper on the basis of dielectric spectrum detecting theorem. The technical criterions and the applied conditions are determined. The behaviors of the photoelectron of various film materials and on the condition of different laser energy are obtained with this apparatus. The time properties of the behaviors of the photoelectron of different silver halide materials are studied. The relations between the saturation figure of the photoelectron excitation and the property figure of the material responding to the exposure are discussed. The relations between the generation of the photoelectron and the laser energy are discussed in detail. The laws of the quantum efficiency of the exposure are obtained. The effects of the lifetime of the photoelectron on the macro parameters of some silver halide are discussed. According to the decay velocity, we divide the decay process of the free photoelectron and discuss the effects of the loss factors on the decay of the photoelectron. We give the decay kinetics process of free photoelectron in the end.更多还原
