Abstract

In this paper, we use a perylene diimide derivative serving as a destructive and an absorption layer of the “black cathode” of an organic light-emitting device (OLED). A thin and semitransparent metal between the electron transport layer and the perylene diimide is used for better electron injection and also serves as the destructive interference. The thickness of such layer is critical since thinner metal results in lower reflectance, but higher diving voltage due to worse electron injection. To enhance the electron injection capability, the thickness of the thin metal increases which in turns to increase the reflectance. Here, we used a double-metal configuration to decrease the reflectance and maintain the electron injection capability at the same time.
