| Summary: | We studied silver nanoparticles (Ag NPs) as an n-type dopant in the charge generation connector of
tandem organic light-emitting diodes. Due to the localized surface plasmonic resonance and
quantum size effects, Ag NPs are more active and easy to lose electron comparing to bulk or film
forms of Ag, and can work as excellent n-type dopant. For the tandem device with Ag NPs in the
charge generation layer, the current efficiency is more than doubled and the driving voltage is less
than twice compared to one single emission unit device. |
