Abstract
The present disclosure provides multilayered hole injection structures including one or more layers of oxides for application in an organic electroluminescent device. The layered structures include an insulating metal oxide such as AlOincluding a transition metal oxide to lower the hole injection barrier and enable hole transfer which is sandwiched between the conductive aluminum layer and a hole transport layer. The layered structure may also include a tri-layered structure stacked sequentially including a first electrically conductive layer, an insulating metal oxide and a hole injection layer material selected from a group of transition metal oxides.
