In this work, we have demonstrated a top‐emission green quantum dot light‐emitting diode (QLED) with dielectric‐metal‐dielectric (DMD) structure as transparent cathode, which consisted of ytterbium (Yb)‐doped molybdenum oxide (MoO3)/Yb:Ag/MoO3. The DMD‐QLED exhibited a reduced operational voltage and higher efficiency by 1.43‐folds enhancement in external quantum efficiency relative to reference QLED...
