摘要

The bromide (Br) ions on a conjugated polyelectrolyte (CPE) PFN-Br were converted to tetrafluoroborate (BF4) or hexafluorophosphate (PF6) ions through anion exchange to obtain two polymers PFN-BF4 or PFN-PF6 for surface engineering of zinc oxide nanocrystals (ZnO NCs). The ionic groups on CPEs can form permanent dipoles to facilitate charge injection from ZnO NCs to cesium lead bromide (CsPbBr3) NCs emitters and therefore promote luminescent properties of inverted perovskite light-emitting diodes (PeLEDs). The incorporation of CPEs also helped to passivate the defects of ZnO NCs films, improve contact between ZnO and perovskite layers, and prolong carrier lifetime of CsPbBr3 NCs. PeLEDs based on different CPEs were fabricated and evaluated.
