| Outline of Final Research Achievements |
Using single-molecule spectroscopy we studied and controlled the photoresponse of molecular complexes, such as aggregates, molecular crystals and conjugated polymers, as well as their semiconducting counterparts, such as quantum dots, and hybrid systems composed of noble metal nanoparticles and organic dyes. The results include conformational and spectroscopic characterization of poly(phenylene vinylene) and polyfluorene conjugated polymers, origin and suppression of defect emission and characterization of band-edge emission in I-III-IV semiconductor quantum dots, characterization of blinking, emission quantum efficiency and electroluminescence in halide perovskite nanocrystals, effect of enhancement of resonant energy transfer between organic dyes by localized plasmons and study of triplet exciton diffusion, phosphorescence and of triple-triplet annihilation and photon upconversion in molecular solids.
