Abstract
Polymeric light-emitting diodes (PLEDs) have drawn considerable interest since its discovery due to their potential as a means for flat-panel display. However in most polymer materials, the mobility of electrons is smaller than that of holes. It causes imbalanced carrier injection in polymeric electroluminescence (EL) devices [1]. Here, we report the use of organic/inorganic heterostructure to fabricate the p-n heterojunction devices. The heterostructure provides a new approach for constructing high performance electroluminescence devices which improve the balance of hole and electron injection.
