Abstract:
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.

Claim (Index 11):
A method for manufacturing the zinc oxide ink according to  claim 1 , including:\n preparing an ethanol solution of zinc oxide nanoparticles; adding a ligand compound into the ethanol solution of the zinc oxide nanoparticles, stirring the solution and adding ethyl acetate therein to precipitate zinc oxide nanoparticles,\n wherein the obtained zinc oxide nanoparticles are loaded with ligands derived from the ligand compound, and the ligand compound is selected from aliphatic compounds having a carbon chain of three or more carbon atoms; and \n the ligand compound has a cross-linkable group at a site close to a coordination atom; and dissolving the zinc oxide nanoparticles loaded with the ligands in a mixed solvent comprising a volatile solvent and a non-volatile solvent, and adding an initiator and a cross-linking agent therein to form the zinc oxide ink.
