doi:10.7517/j.issn.1674-0475.1999.02.104

Abstract

Abstract: The effects of different iodide content of cubic emulsion microcrystal on the sensitivity, ionic and photoconductivity were studied.It was shown that the sensitivity and ionic conductivity of emulsions increased with the iodide content increase in the range of 0～1%,the lifetime of photoelectron of emulsions constantly increased with the iodide content increase in the range of 0～2.4%.

Key words: iodide content, cubic microcrystal, photographic properties, ionic conductivity
