摘要
In this study we demonstrate inverted organic light-emitting diodes (OLEDs) utilizing highly conductive polyethylene dioxythiophene-polystyrene sulfonate as a buffer layer to a radio-frequency sputter-deposited indium-tin-oxide as the anode. In comparison to an entirely small-molecule-based reference, a reduction in operation voltage of 8.4 V at superior efficiencies of 4.2 cd/A and 1 lm/W obtained at 1.000 cd/m(2) was achieved. The inverted cell configuration is desirable for next-generation active-matrix OLED displays. (C) 2003 American Institute of Physics.
