Zinc oxide based nano-particle ink and quantum dot light-emitting diode

The invention provides zinc oxide based nano-particle ink. The zinc oxide based nano-particle ink comprises zinc oxide based nano-particles, a first solvent and a second solvent, wherein the zinc oxide based nano-particles are provided with ligands; the ligands are glycols, alcohol amines from C2 to C4 or acid amides from C1 to C4; the first solvent is alcohol ether and/or saturated monohydric alcohols with the boiling point being 160-250 DEG C; the second solvent is diol; the content of the first solvent is 60wt%-96wt%; and the content of the second solvent is 3wt%-30wt%. The provided zinc oxide based nano-particle ink is suitable for ink-jet printing, and is excellent in printing effect; a sprayer is not blocked after printing for multiple hours continuously; and a printing ink droplet track does not offset. 本申请提供种氧化锌基纳米颗粒墨水，包括：氧化锌基纳米颗粒，所述氧化锌基纳米颗粒具有配体，所述配体为二醇类、C2到C4的醇胺、或C1到C4的酰胺；第溶剂，所述第溶剂为醇醚和/或沸点在160～250℃的饱和元醇；第二溶剂，所述第二溶剂为二醇；所述第溶剂的含量为60wt％～96wt％，第二溶剂的含量为3wt％～30wt％。本申请中所提供的氧化锌基纳米颗粒墨水，适合于喷墨打印，且打印效果优良，连续打印多小时后
