| Abstract: |
| A high-effective bottom anode is essential for high-performance top-emitting organic light-emitting devices (OLEDs). In this
paper, Ag-based top-emitting OLEDs are investigated. Ag has the highest reflectivity for visible light among all metals, yet
its hole-injection properties are not ideal for anodes of top-emitting OLED. The performance of the devices is significantly
improved using the molybdenum oxide as anode buffer layer at the surface of Ag. By introducing the molybdenum oxide, the hole
injection from Ag anodes into top-emitting OLED is largely enhanced with rather high reflectivity retained. |
