Abstract :
We have fabricated and investigated the effect of CdSe/ZnS quantum dot (QD) concentrations on self-assembly hybrid organic/inorganic light emitting diodes (QD-OLEDs). The uniform distribution of QDs with controllable density was achieved using the conventional spin-coating method. There was a QD threshold concentration below which there was no emission from the QDs. The estimated QD concentration was around 9 × 1011 cm-2 for the best performance of QD-OLED. The QD emission was increased about three times by annealing of QD-OLED.
