Abstract

Abstract: Cubic AgBrI microcrystals (0.25 m) were prepared by doublejet method and the distibution of development centers in the microcrystals containing stabilizer TAI was measured by arrested development and electron microscope.The results indicate that the sensitization by TAI is obvious in S+Au sensitized AgBrI cubic emulsions but the sensitivity is not changed by TAI in unsensitized emulsions. The presence of TAI increases the grain fraction of development centers containing one and twocenterpergrain class.

Key words: cubic AgBrI microcrystals, distribution of development centers, photographic properties
