Abstract
We study the processes of interaction between molecules and H-aggregates of a dye adsorbed at the surface of AgBr and AgBrI emulsion microcrystals (EMC). Methods of the low-temperature (T = 4.2 K) luminescence enable to associate the “self-desensitization” with the mechanism conditioned by the interaction of Н- and J-aggregates of the dye with its molecules, which results in the decay of the spectral sensitivity of emulsions employing organic dyes. Methods of low temperature (T = 77 K) luminescence show the interaction of the first excited state of the Н-aggregates with the triplet state of the molecular dye, which indicates the process of the excited Н-aggregates’ energy dissipation through the triplet state of its molecules.
