Abstract

CuPc:C₆₀ Organic-Fullerene composites together with metals such as Au are found to form efficient hole injection structures for organic light-emitting diodes. C₆₀ concentration of 30 wt.% yielded optimum device characteristics including low driving voltage, high current efficiency, and high thermal stability. In the case of Au/CuPc:C₆₀ anode structure, extremely high current efficiency of ~ 8.7 cd/A and low operating voltage (i.e. 20 mA/cm² at ~8V) has been achieved in a simple bi-layer device using Alq as emitter. Through a study on single carrier devices, the versatility of the composite injection structure is attributed to that C₆₀ in the composite layer facilitate hole transfer from the metals to the composite whereas CuPc facilitate hole transport and transfer to a hole transport layer.
