Abstract

AbstractTop‐emitting organic light emitting diodes (Top‐OLED) were made with platinum (Pt) and praseodymium oxide (Pr2O3) as the anode buffer. ITO on thin Al was used as the transparent cathode. Efficient Top‐OLED were obtained with a microcavity design. It was found that this Top‐OLED was highly non‐Lambertian. It emitted 10% more photons than conventional bottom‐emitting‐ OLED after integration over all angles.
