TL;DR: The quantitative analysis shows that the external quantum efficiency as a function of the host layer thickness follows the characteristic of the long-range Förster process.
Journal ArticleDOI
Quantum Dot Light-Emitting Diode with Quantum Dots Inside the Hole Transporting Layers
Kheng Swee Leck,Y. Divayana,Dewei Zhao,Xuyong Yang,Agus Putu Abiyasa,Evren Mutlugun,Yuan Gao,Shuwei Liu,Swee Tiam Tan,Xiao Wei Sun,Hilmi Volkan Demir +10 more
TL;DR: A hybrid, quantum dot (QD)-based, organic light-emitting diode architecture using a noninverted structure with the QDs sandwiched between hole transporting layers (HTLs) outperforming the reference device structure implemented in conventional non inverted architecture by over five folds and suppressing the blue emission that is otherwise observed in the conventional structure because of the excess electrons leaking towards the HTL.
