摘要： A novel class of low reflectivity, high transparency, non-metallic cathodes (1) useful for a wide range of electrically active, transparent organic devices is disclosed. As a representative embodiment, the highly transparent non-metallic cathode (1) of an OLED employes a thin film of copper phthalocyanine (CuPc) (6) capped with a film of low-power, radio-frequency sputtered indium-tin-oxide (ITO). The CuPc prevents damage to the underlying organic layers during the ITO sputtering process. Due to the low reflectivity of the non-metallic cathode, a non-antireflection-coated, non-metallic-cathode-containing TOLED is disclosed that is 85 % transmissive in the visible, emitting nearly identical amounts of light in the forward and back-scattered directions.
