Abstract

In this presentation we present results based on electrophosphorescence OLEDs using solution processes techniques. One of the limitations obtaining high efficiency from a single layer electrophosphorescence OLED is the relatively poor charge balanced properties. We investigate the effect of incorporation of hole as well as electron moieties within the host polymeric binder is terms of injection transport and quenching properties and correlate the results with device performance. We also present results on several alternative structures studied in order to improve device efficiency
