E.M. acknowledges BAGEP award ; Nonradiative energy transfer (NRET) is an alternative excitation mechanism in colloidal quantum dot (QD) based electroluminescent devices (QLEDs). Here, we develop hybrid highly spectrally pure QLEDs that facilitate energy transfer pumping via NRET from a phosphorescent small organic molecule-codoped charge transport layer to the adjacent QDs. A partially codoped exciton funnelling electron transport layer is proposed and optimized for enhanced QLED performance while exhibiting very high color purity of 99%. These energy transfer pumped hybrid QLEDs demonstrate a 6-fold enhancement factor in the external quantum efficiency over the conventional QLED structure, in which energy transfer pumping is intrinsically weak. ; Singapore National Research Foundation NRF-RF-2009-09 NRF-CRP-6-2010-02 Agency for Science Technology & Research (ASTAR) 61006037 61076015 Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) 109E002 109E004 110E010 110E217 European Science Foundation (ESF) Turkish Academy of Sciences BAGEP award Science and Engineering Research Council EU-FP7 Nanophotonics4-Energy NoE
