Electronic properties of chemically produced silver clusters were studied using an internally sulfur-sensitized core-shell emulsion. Upon reduction sensitizing the shell of this emulsion with either dimethylamineborane or high pH the internal speed was enhanced. This is clear evidence that the surface silver clusters are hole removing sites. For our materials and experimental conditions, no evidence was found to support the hypothesis that any of the chemically produced silver clusters, except for those leading to fog, had the characteristics of irreversible electron traps.
