Blue ZnSeTe quantum dot light-emitting diodes with low efficiency roll-off enabled by an in situ hybridization of ZnMgO nanoparticles and amino alcohol molecules

Abstract

ZnSeTe quantum dots (QDs) have been employed as promising emitters for blue QDs-based light-emitting diodes (QLEDs) due to their unique optoelectronic properties and environmental friendliness. However, such QLEDs usually suffered...

Shelf-Stable Green and Blue Quantum Dot Light-Emitting Diodes with High Efficiencies

“…The 2-(2-aminoethoxy)­ethanol (AEE) molecule terminating with an amine group and a hydroxyl group on each end is selected as a model system. The amine group is widely used to passivate the surface defects of the ZnO nanocrystals. − The hydroxyl group enables the amine-capped O-ZnO nanocrystals to disperse in alcoholic solvents.…”
