摘要：
Highly transparent and efficient red phosphorescent inverted top-emitting organic light emitting diodes were investigated by using a surface-modified tungsten oxide (WO(3))/silver/WO(3) (WAW) anode. A thin buckminsterfullerene (C60) dipole layer was introduced for the surface treatment of the WAW anode, and the thickness of the surface-modified WO(3) was controlled to optimize the WAW anode for hole injection. The optimum thickness of the surface-modified WO(3) was 5 nm, and the C60 dipole layer further improved the hole injection from the WAW anode to the hole transport layer.
