摘要

The photographic emulsions, which consist of suspensions of silver iodobromide nanoparticles in fish gelatin, were made by a double-jet method. The average sizes of the particles obtained by XRD measurement and TEM observation were 16 nm and 14.3 nm, respectively. The microwave photoconductivity measurement showed two first-order kinetics processes. The electron lifetime in the first process shortened obviously, indicating a mass of shallow traps on the nanoparticle surfaces. The second process was a slower decay one, which was considered as electron trapping followed by the reaction of trapped electrons with interstitial silver ions.
