In this work we describe the development of single-organic-layer LED's based on doped-polymers which have high efficiency (>1% quantum efficiency measured out the back of the glass) and low drive voltage (<10 V at 100 cd/m2). The LED's are based on poly (N-vinylcarbazole) (PVK), into which various electron transport agents and emitting centers have been doped for red, green and blue emission. Proper ITO surface preparation is crucial for achieving low turn-on voltages. We will then use these LED's as model systems for the integration of multiple spin-coated organic layers onto a single substrate (for integrated red, green, and blue emitters) and for the integration of OLED's and amorphous silicon TFT's on novel substrates.
