The Chemical Sensitization of Silver-Iodide Emulsions^*

* Communication No, 2077H from the Kodak Research Laboratories.

Abstract

The sensitivity of silver-iodide emulsions is shown to be dependent upon the silver-complexes present at the surface of the grains. It is suggested that these complexes increase the useful absorption of light as well as increasing halogen acceptance in the system. No internal image could be found in these emulsions; nor was it possible to sensitize them by a sulphur-digestion although the rate of printing-out was increased.
