Abstract

The specific features of spectral sensitization of photoinitiated reduction of nanosized AgHal grains by a carbocyanine dye were studied in pools of reverse micelles. The process was found to be effected by the dye adsorbed on nanosized grains in the monomeric B-trans state. It was shown that the adsorbed dye not only played the role of a sensitizer but also effectively stabilized the size of nanocrystals. As the result, hybrid nanosystems of the type nanosized grain-dye were formed, which could exist outside the protective micellar shell and could be isolated from micelles and transferred to any matrix.
