Abstract EN
The optical properties and charge transfer mechanism of poly (9,9′-di-n-octylfluorenyl-2.7-diyl) (PFO)/ZnO thin films have been investigated.
The ZnO nanorods (NRs) were prepared via a microwave technique.
The solution blending method was used to prepare the PFO/ZnO nanocomposites.
X-ray diffraction (XRD) and field emission scanning electron microscope (FE-SEM) were used to determine the structural properties, while UV-Vis and photoluminescence (PL) were employed to investigate the optical properties of the films.
XRD patterns confirmed that there was no variation in the structure of both PFO and ZnO NRs due to the blending process.
FE-SEM micrographs displayed that ZnO NRs were well coated by PFO in all nanocomposite films.
The absorption spectra of the nanocomposite thin films exhibited a red-shift indicating the increment in conjugation length of the PFO/ZnO nanocomposite.
Significant quenching in the emission intensity of PFO was observed in fluorescence spectra of the nanocomposite films.
This quenching was attributed to efficient charge transfer in the PFO/ZnO nanocomposites, which was further supported by the shorter PL lifetime of PFO/ZnO than that of the PFO thin film.
The continuous decline in PL intensity of these nanocomposites is attributed to homogenous dynamic quenching between PFO and ZnO NRs.
