Grant-in-Aid for Scientific Research (A),2015.04 - 2018.03,Ultra high efficiency organic-inorganic hybrid light emitting device
All-inorganic perovskite (CsPbX3, X = Cl, Br, or I) quantum dots (QDs) have recently attracted considerable interest for light-emitting device (LED) applications such as thin film displays and solid-state lighting, owing to electroluminescence emission with narrow full width at half maximum (FWHM), tunable color properties in the visible light range, and ease of solution processability. Here, we demonstrated low driving voltage and high efficiency CsPbBr3 QDs light-emitting devices (QD-LEDs) using a ligand exchange method and washing process with an ester solvent c to remove excess ligands. The LED with ligand exchange CsPbBr3 QDs exhibited a low turn-on voltage of 2.6 V and EQE of 8.7%. Control of the interfacial perovskite QDs through ligand removal and energy level alignment in the device structure are promising methods for obtaining high PLQYs in film state and high device efficiency.
