Abstract
Official abstract text for this publication.
In an aspect, an organic light emitting diode device including a first electrode, a second electrode facing the first electrode, and an emission layer positioned between the first electrode and second electrode, wherein the first electrode includes samarium (Sm) is provided.
First claim
Opening claim text (preview).
What is claimed is: 1. An organic light emitting diode device, comprising a first electrode; a second electrode facing the first electrode; and an emission layer positioned between the first electrode and second electrode, wherein the first electrode is a single layer and is an alloy of samarium (Sm), and silver (Ag), wherein the samarium (Sm): the silver (Ag) is in a volume ratio of about 1:15 to about 1:20. 2. The organic light emitting diode device of claim 1 , wherein the single layer has a thickness of about 30 Å to about 150 Å. 3. The organic light emitting diode device of claim 1 , wherein: the first electrode has light transmittance of greater than or equal to about 60% in a wavelength region of about 450 nm to about 700 nm. 4. The organic light emitting diode device of claim 3 , wherein the first electrode has light transmittance of about 60% to about 95% in a wavelength region of about 450 nm to about 700 nm. 5. The organic light emitting diode device of claim 1 , wherein the second electrode comprises a reflecting electrode, and the emission layer is configured to emit a white light. 6. The organic light emitting diode device of claim 1 , wherein the second electrode comprises a transparent electrode, and the emission layer is configured to emit a white light. 7. The organic light emitting diode device of claim 1 , wherein the first electrode is a cathode.
