Abstract: | Spectral and luminescent properties of an indotricarbocyanine dye are studied in solutions and after deposition on quartz or silicon substrates. It is found that the dye molecules self-assemble in aqueous EtOH solutions to form H*-aggregates. The absorption band of the H*-aggregates shows a hypsochromic shift of 192 nm (5291 cm–1) relative to the absorption maximum of dye monomers (706 nm) and has a full width at half maximum of 21 nm (797 cm–1). The morphology of the H*-aggregates of the indotricarbocyanine dye is studied for the fi rst time. It is found that the aggregates are rod-like species ~10 nm high, 100 nm wide, and several micrometers long. H-aggregates with a fl uorescence maximum at 560 nm and Stokes shift of 325 cm–1 in addition to non-fl uorescent H*-aggregates form in aqueous EtOH solutions and are nanoparticles with a height of 1–3 nm and lateral dimensions of ~100 nm. |
