Paper Abstract

The time-resolved photoelectron spectra of spectrally sensitized cubic AgCl emulsion are detected with microwave absorption and dielectric spectrum detection technique. The decay process of photoelectron is accelerated and becomes faster than that of the unsensitized sample since the concentration of interstitial Agi + ions is increased when the dye molecules are adsorbed onto the surface of crystal. The influence of temperature condition on the photoelectron decay process is obtained. Results show that the dye adsorption degree is varied when the sensitizing temperature differs, then the decay dynamic changes. The optimal temperature condition is in 450C in which the adsorption of dye has a larger influence on crystal property and the photoelectron decay is fastest. When lower or higher than this condition, the adsorption degree is poor or the dye molecules have a tendency to form bigger dye-aggregates, then the variance of interstitial Agi + ions is less than that in 450°C and causes a slower photoelectron decay process.
