Effect of ZnO Composition on the Electrical Properties of MEH-PPV: ZnO Nanocomposites Thin film via Spin Coating

Organic semiconductor have been commercialized for optoelectronic device application particularly in organic light emitting diodes (OLEDs). Poly [2-methoxy-5(2' - ethylhexyloxy)-1, 4- phenylenevinylene), MEH-PPV used in optoelectronic devices because it is easily synthesized and deposited in high molecular weight and good purity. The MEH-PPV: ZnO nanocomposites was prepared by spin coating method at room temperature. The MEH-PPV: ZnO nanocomposites thin film was investigated at different ZnO compositions. The electrical properties showed the ZnO composition at 0.2 wt% exhibits the highest conductivity of nanocomposites thin film (7.40×10^-1 S. cm^-1) and suitable applied in optoelectronic devices.
