摘要：

Among the novel finite size effects observed in a series of nanoscale (25-100 nm) semiconducting polymer heterojunctions, such as polyquinoline(PPQ)/poly(p-phenylene vinylene) (PPV), is the reversible switching of electroluminescence (EL) colors (orange/red <-> green) by the applied voltage. The finite size effects are related to the charge carrier ranges in semiconducting polymers and are expected to be important in electronic and optoelectronic devices from organic semiconductors.
