Spectral Sensitization, Supersensitization and Ultrafast Exciton Trapping on AgBr Semiconductor Surface

摘要

The fast electron photo-injection rate from the adsorbed dye to AgBr was found to be dependent on the type of AgBr surface, size of grains, and pAg of emulsion. Ultrafast exciton trapping is discussed in terms of dimensionality of J-aggregates.
