Photophysical properties and energy transfer mechanism in PFO/TiO2 /MEH-PPV nanocomposite thin films
Improvement in photophysical properties of poly-9,9-dioctylfluorene (PFO)/10 wt. % TiO2 nanoparticle thin film as a result of systematic additions of poly(2-methoxy-5(2-ethylhexyl)-1,4-phenylenevinylene (MEH-PPV) were investigated. The nanocomposite blends were prepared with additions of MEH-PPV...

| description | Improvement in photophysical properties of poly-9,9-dioctylfluorene (PFO)/10 wt. % TiO2
nanoparticle thin film as a
result of systematic additions of poly(2-methoxy-5(2-ethylhexyl)-1,4-phenylenevinylene (MEH-PPV) were investigated.
The nanocomposite blends were prepared with additions of MEH-PPV up to 3.0 wt. % of the total weight. All blends
were prepared using the solution blending method and subsequently spin-coated onto glass substrates. The UV-Vis
absorption and photoluminescence characterizations showed the intensification of the primary-color emissions of the
thin films with the Förster resonance as the primary energy transfer mechanism from PFO to MEH-PPV. Important
photophysical parameters, such as the Förster radius (Ro
) excited state lifetime (τ), fluorescence quantum yield of the
donor (φ), quenching constant (ksv), quenching rate constant (kq
), distance between the donor and acceptor (R), energy
transfer lifetime (τET), and energy transfer rate (kET) display better values with increasing the contents of MEH-PPV
by 2.5 wt. %, suggesting an ordered improvement on the photophysical properties of the thin film. Finally, a possible
underlying mechanism describing the enhancement of the photophysical properties was proposed. |
