Zinc oxide-based particle ink and quantum dot light-emitting dioxide

The invention provides zinc oxide-based particle ink which comprises zinc oxide-based nano particles, a first solvent, a second solvent, a third solvent and a fourth solvent. The zinc-oxide-based nanoparticles are provided with ligands. The ligands are dialcohol, C2-C4 hydramine or C1-C4 hydramine; the first solvent is alcohol ether and/or saturated monohydric alcohol, the boiling point of whichis 160-250 DEG C; the second solvent is dialcohol; the third solvent is saturated monohydric alcohol, the boiling point of which is 70-155 DEG C; the fourth solvent is fluorocarbon alcohol; the content of the first solvent is 40-60wt%, the content of the second solvent is 1-10wt%, the content of the third solvent is 10-30wt% and the content of the fourth solvent is 5-30wt%. The zinc oxide-based particle ink provided by the application is suitable for spraying ink and printing and is excellent in printing effect, and the printed ink droplet track is not deviated if printing for many hours continuously. 本申请提供种氧化锌基纳米颗粒墨水，
