Abstract

Organic Electroluminescence device, which have the single-layer structure of ITO(indium-tin-oxide)/MEH-PPV (Poly[2-(2'-ethylhexyloxy )-5-methoxy-1,4-pheny lenevinylene])/Al(aluminium) and ITO/MEH-PPV/$Alq_3$(tris-8-hydroxyquinolinato aluminium)/Al were fabricated and electrical properties were investigated. Experimental results, in single-layer structure, shown that turn on voltage is about 12 V, and current density increases as a function of increasing temperature. It was explained by thermionic emission. In double-layer structure, thickness $200\AA$ of $Alq_3$ is shown electrical properties that turn on voltage is about 11 V, and current density decreases as a function of increasing temperature.ࠀȀ 耀Ѐ€
