PHOTOGRAPHIC PROPERTIES OF ULTRAFINE AgBrI EMULSIONS

doi:10.7517/j.issn.1674-0475.1999.03.270

Abstract

Abstract: ;Three ultrafine AgBrI emulsions were prepared with different sizes. It was observed that the ionic conductions were directly proportional to the grain size, whereas the photoelectron life times were inversely proportional to the grain size. The sensitivities and contrasts of these emulsions would be increased obviously when they were sensitized with (NH₂)CSO₂. The chemical sensitized effect of (NH₂)CSO₂ is better than sulfursensitization, goldsensitization and sulfurplusgoldsensitization.

Key words: ultrafine, photographic property, ionic conduction, photoelectron conduction
