Abstract

Abstract: The effect of J-aggregate on the electron trapping process by dye positive holes was investigated by means of ESR.The oxidation potentials of dyes studied in this paper are of very close values,but quite different in the decay curves of light-induced ESR signals of these two dyes in AgBr emulsion.This fact could be attributed to the different aggregate state of dye on the AgBr surface.

Key words: Dye J-aggregate, dye positive holes, electron spin resonance, the oxidation potential of a dye
