Abstract: A series of Ca2+ doped AgBr and Ag[Br,I], emulsions was prepared.The effect ofdoped Ca2+ ions with differents on the spectra of dielectric loss and photographic sensitivities of AgBr and Ag[Br,I]emulsions was studied.The dielectric absorption peaks of silverhalide emulsions shift to lower frequency due to the doping with。The sensitivitiesof Ca2+.doped emulsions increase in certian degree.

Key words: silver halide, doping, dielectric loss
