Optical Properties of Nanoporous Aluminum Oxide Activated by Molecular Clusters of Pseudoisocyanine Dye

The hybrid nanomaterials based on inorganic matrix and organic compound with customizable properties have practical potential in the field of new developments in biological and chemical sensors, photonic and solar cell devices, as well as laser media. The optical properties of molecular clusters so called J-aggregates embedded in nanoporous aluminum oxide in presence of silver plasmonic nanoparticles were studied. The unique technique for obtaining nanoporous aluminum oxide on the island silver film was proposed. The optimal parameters of the impregnation of nanopores in the ethanol solution of pseudoisocyanine dye for the J-aggregate formation have been studied. The resonant transfer of optical energy from the oxygen vacancy in aluminum oxide to organic molecules was observed in the resulting hybrid films.
