Using solvent based surface engineering of sol-gel derived ZnO electron injector, red QLEDs with a current efficiency of
32.6 cdA-1 and a power efficiency of 18.6 lmW-1 at 1000 cdm-2 for Cd based QDs. We also report dark red electroluminescent InP/ZnS QDs (x,y = 0.672, 0.325)) with a maximum current and power efficiency of 3.6 cdA-1 and 4.7 lmW-1respectively.
