title: Study on current–voltage characteristics of OLEDs using  Alq3 as the electron transport layer
creator: Nguyen, Kien Cuong
subject: Engineering Physics
description: This paper describes changes in current-voltage (I-V) characteristic of an organic lightemitting  device (OLED) stacked as a multilayer of ITO/MEH-PPV/Alq3/Al. The ordered, stacked  ITO/MEH-PPV/Alq3/Al multi-layers were fabricated by spin-coating and thermal vacuum  evaporation methods. First, dissolved MEH-PPV solution was spin-coated on ITO-electrodes that  had been covered on a glass-slide. Subsequently, an Alq3 layer was evaporated thermally on the  MEH-PPV-coated layer. Finally, an Al-electrode was evaporated also on the electron transport  layer. UV-vis absorption and photoluminescent characterization of the MEH-PPV and Alq3 layer  as well as their surface images were performed. All spectra obtained revealed the MEH-PPV and Alq3 were deposited as given structure. The I-V characteristics show the present of the Alq3-electron transport layer deposited between the MEH-PPV emissive layer and Al-cathode could enhance current-voltage characteristic reducing the threshold voltage and turn-on voltage.    Keywords: UV-vis absorption, photoluminescence, electron transport layer, current-voltage characteristics.
