The performance of top-emitting organic light-emitting diodes depends not just on the choice of the transparent cathodes but also on their techniques of formation. Compared to the damage induced by radio frequency sputtering of indium-tin oxide cathode, that induced by DC sputtering was verified to be less severe and relatively independent of the sputtering power. Consequently, a high DC sputtering power of 120 W could be employed to achieve a high deposition rate of 0.1 nm/s. Adequate emission efficiency was maintained, even with a relatively thin 7-nm copper (II) phthalocyanine buffer layer.
