Effect of Hole Transporting Layer doped with salts on Performance of Polymer Electroluminescent devices |
| 초록 |
Poly(p-phenylene vinylene) has studied as not only emissive material but also hole transporting material in polymer light-emitting diodes. Because PPV is non-soluble polymer at any solvent it can be used as an hole transporting layer (HTL) in multilayer structure of electroluminescent devices. After thermal conversion of PPV precursor into PPV, we spin-coated poly[2-methoxy-5-(2'-ethylhexoxy)-p-henylene vinylene] (MEH-PPV) as an emitting layer on it. EL devices using the PPV doped with organic, inorganic salts as HTL showed great luminance effciency. The salts in PPV polymer chains formed local dipoles under the electrical field and it affect the performance of the EL devices. Energy transfer of PPV to MEH-PPV may occur on the interface between PPV and MEH-PPV. |
