چکیده انگلیسی
In this study, we report the electroluminescence and photoluminescence of poly[2-methoxy-5-(2-ethylhexyloxy)-p-phenylene vinylene] (MEH-PPV) and 4-cyano-4â²-N-heptylbiphenyl (7CB) blends in the ratios of 0-90Â wt% by drop-coating processes. The corresponding characterization of polarized optical microscope, electroluminescence, photoluminescence and atomic force microscope of different blending ratios of MEH-PPV/7CB are systematically carried out in this study. The optimal composition of 6/4 ratio in MEH-PPV/7CB exhibit the highest luminescence, which is almost ten times than that of pure MEH-PPV due to the fact that 7CB could be a barrier to avoid the aggression of MEH-PPV. The novel blending system demonstrate a potential approach for synthesizing the MEH-PPV/7CB composite film for electroluminescent device applications.
