Abstract
This paper focuses on the spectroscopic studies and self-assembly behavior of zinc octaethylporphyrin (ZnOEP) doped semiconducting [poly(N-vinylcarbazole) (PVK)] polymer nanoparticles (NP) using steady state and time-resolved spectroscopy. The bathochromic shift of both Soret (by 12 nm) and Q bands (by 6–8 nm) in the absorption spectra and shortening of the porphyrin lifetime indicate the J-aggregation of porphyrin molecules in the ZnOEP doped PVK NP system. The significant quenching of fluorescence spectrum and the shortening of decay time of the PVK host unambiguously confirm an effective energy transfer (above 90%) from PVK to ZnOEP in the nanoparticles.
