[MEET2-1(Invited)] Quantum Dot Electroluminescence to Achieve Saturated Colours for REC2020 Compatibility

*Poopathy Kathirgamanathan1, Muttulingam Kumaraverl1 (1. Brunel University London (UK))

Keywords:Electroluminescent quantum dots, Cd Free Quantum Dots, InP/ZnS QDs, CdSe/ZnSe/ZnS QDs, Qleds

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.
