In organic light-emitting diodes, an order of magnitude enhancement of the external quantum efficiency is observed without reduction in the charge-carrier mobility resulting in radiances of up to 5 W str(-1) m(-2) at 800 nm.enNIR; energy transfer; fluorescence; organic LEDs[SDGs]SDG7journal article10.1002/adma.201600851271665972-s2.0-84982976272WOS:000382480100011https://api.elsevier.com/content/abstract/scopus_id/84982976272
