Abstract
Official abstract text for this publication.
Disclosed is an organic light emitting diode device including an anode, a cathode, an emission layer between the anode and the cathode, and a buffer layer positioned between the emission layer and the anode. The buffer layer includes an oxide, fluoride, quinolate, or acetoacetate compound of an alkaline metal or an alkaline-earth metal, as well as a material having a work function of about 2.6 to about 4.5 eV. The buffer layer also has a thickness of about 30 Å to about 400 Å.
First claim
Opening claim text (preview).
What is claimed is: 1. An organic light emitting diode device, comprising an anode, a cathode, an emission layer between the anode and the cathode, and a buffer layer positioned between the emission layer and the anode, the buffer layer comprising a first material that is an oxide, fluoride, quinolate, or acetoacetate of an alkaline metal or an alkaline-earth metal, the buffer layer further comprising a second material having a work function in a range from about 2.6 to abou…
