Absorption and photoluminescence (PL) spectra of the polymer thin films prepared from different solvents were measured. It was concluded from the UV-Vis absorption and PL spectra that the optical properties of MEH-PPV films strongly affected by solvents used for spin coating. A strong photoluminescence quenching was observed in (1:4) MEH-PPV: [6,6]-Phenyl C61-butyric Acid 3-ethylthiophene Ester (Modified Fullerene) composite which provides evidence of photoinduced charge transfer. Further, with Atomic Force Microscope (AFM) it has been demonstrated that the surface morphology of the MEH-PPV: Modified fullerene thin films are strongly dependent on the preparation condition (solvents).
