Abstract

ITO modification using heat treatment for low driving voltage of OLEDs is proposed. Annealing of a regular ITO layer at 250°C in a GB led to both structural and surface changes. As a result, ITO work function was decreased, reducing the injection barrier to holes and facilitating the tunneling of carriers. The decrease of driving voltage with an increase of annealing time was obtained.
