Development of measurement method of dose of silver clusters on silver halide grains by utilizing radioisotope species

We developed measurement method of dose of silver clusters on silver halide grains by utilizing reaction, benzenethiosulphonate converts small silver clusters to silver sulfides. We replace sulfur atom of benzenethiosulphonate to radioisotope 35S and measure dose of Ag235S converted from small silve...

Summary:We developed measurement method of dose of silver clusters on silver halide grains by utilizing reaction, benzenethiosulphonate converts small silver clusters to silver sulfides. We replace sulfur atom of benzenethiosulphonate to radioisotope 35S and measure dose of Ag235S converted from small silver clusters. By using this method, we demonstrated on reduction sensitization, photographic sensitivities correspond to dose of silver clusters. We modified this method for high sensitivity measurement by stopping reaction intermediately and data-fitting to formula derived from chemical kinetics.
