Red, green, and blue quantum dot LEDs with solution processable ZnO nanocrystal electron injection layers

Author affiliations

Abstract

ZnO nanocrystals are presented as an electron injection layer for red, green, and blue light-emitting diodes (LEDs) based on core–shell CdSe/ZnS quantum dots (QDs). The deposition of ZnO nanocrystals from isopropanol permits fabricating multilayer QD-LEDs that include both hole and electron transport layers by simple solution processing. The ZnO nanocrystals improve electron injection in the light-emitting QD layer as evidenced from a decreased turn-on voltage and a reduction of emission originating from other layers than the QD layer of the LEDs.
