High-performance 1550 nm polymer-based LEDs on silicon using hybrid polyfluorene-based type-II heterojunctions

We report on the optoelectronic properties of hybrid polymer-based light-emitting diodes integrated on silicon chip. Using a hybrid polyfluorene-based type-II heterostructure host with PbS quantum dots, we achieved efficient room-temperature electroluminescence at telecommunication wavelengths.
