摘要

Spectral patterns of hybrid association in the mixture of colloidal Ag_2S quantum dots (QDs) with an average size of 2.5 to 0.3 nm with J-aggregates of a pyridinium salt of 3,3-di(-sulphopropyl)-9-ethyl-4,5,4,5-dibenzothiacarbocyanine betaine (Dye), prepared by the sol-gel method in gelatin, are investigated. A conclusion about the preferential formation of cis-J-aggregates in the hybrid associates of Dye with Ag_2S QDs is made. The effect of photosensitization of IR luminescence (1000C1300 nm) of colloidal Ag_2S QDs by J-aggregates of Dye is revealed. On the basis of the results, a photosensitization scheme implying the resonance nonradiative transfer of the electronic excitation energy from cis-J-aggregates to the recombination luminescence centers of Ag_2S QDs is suggested.
