ZINC OXIDE INK AND METHOD FOR MANUFACTURING THE SAME, ELECTRON TRANSPORT LAYER AND DISPLAY DEVICE

摘要

The present disclosure provides a zinc oxide ink and a method for manufacturing the same, an electron transport layer and a display device. The zinc oxide ink includes zinc oxide nanoparticles loaded with ligands, wherein the ligand is derived from aliphatic compounds having a carbon chain of three or more carbon atoms and the ligand has a cross-linkable group at a site close to a coordination atom. The zinc oxide ink increases the steric hindrance among the zinc oxide nanoparticles, thereby preventing the aggregation between the zinc oxide nanoparticles, and accordingly and further avoiding the formation of black points in the formed layer. Meanwhile, the ligands have self-crosslinking property and thus form a web-like structure to prevent the formation of pores in the layer due to the rapid volatilization of the solvent, and the quality of the formed layer by using the zinc oxide ink is ensured.
