ENHANCEMENT OF MEH-PPV BY INTRODUCING ANATASETiO2 NANOPARTICLES FOR OLED DEVICE

[摘要] In this work, the characterization and application of thin films composites incorporated titanium dioxide (TiO2) (0.002 and 0.008)g/ml anatase nanostructure with poly [2- methoxy-5-(2’-ethylhexoxy-p-phenylene vinylene] (MEH-PPV) were deposited by spin-coating technique. X-ray diffraction results of MEH-PPV/TiO2 were proved the anatase phase for TiO2 predominantly observed in the composite. The morphology was demonstrated by Field Emission Scanning Electron Microscope (FESEM) images for MEH-PPV and MEH-PPV/TiO2 films and prove agglomerated grains formation. The MEH-PPV/TiO2 nanocomposite mareial have been worked as emissive layer (EML) in the organic light emitting diode (OLED), we obtained high current (7430 μA/mm2) and high electroluminescence spectrum comparative of pristine polymer at the rate of TiO2 (0.008) g/ml .
