摘要：

Organosoluble polyhedral oligomeric silsesquioxanes ( POSS) blending effect on electroluminescence properties of MEH-PPV based polymer light emitting devices was investigated. The surface roughness of POSS:MEH-PPV composite film increased with increasing POSS content. Interfacial area between the light-emitting layer and cathode was favorably enhanced for cathode electron-injection. MEH-PPV blended with POSS would create a better balance between the electron and hole fluxes for POSS/MEH-PPV composite film based devices. This led to greater current efficiency of the POSS:MEH-PPV composite film based device as compared to one with a light emitting layer of MEH-PPV. Organosoluble POSS concentration effects on the PL spectra and EL performances were also studied for the POSS:MEH-PPV composite film based polymer light emitting devices.
