ZnO is a very suitable material as an electron transport layer because it has characteristics of high transparency, electron mobility, and low work function. However, surface defects that occur during synthesis degrade electron mobility. In addition, processability is also reduced due to the low dispersion stability. These include low dispersion stability of inorganic nanoparticles in organic solvents and concurrent poor device processability. To circumvent this issue, new ligands have been designed and applied to the inorganic nanoparticles. Our approach has been successfully validated to achieve high dispersion stabilities for luminescent quantum dots and ZnO-based electron transporting materials. |
