Top-Emitting Organic Light-Emitting Devices Based on Silicon Substrate with High Luminance and Low Turn-on Voltage

We have fabricated a top-emitting organic light-emitting device on silicon substrate with high yellow luminance based on 5,6,11,12-tetraphenylnaphthacene sub-monolayer. It consists of a thin layer of highly conductive silver as the semitransparent cathode and surfaced-modified Ag as the anode. The device turns on at 3V with the luminance of 8.4cd/m². The maximum current efficiency is 1.3cd/A at 6V and the luminance reaches 14790cd/m² at 14V. The performance of the device is excellent in top-emitting organic light-emitting devices according to our knowledge.
