Beschreibung
Zusammenfassung:	The invention provides an ink composition and a preparation method of a quantum dot light- emitting diode. The ink composition comprises: a polar solvent, inorganic nano-particles and an amphiphilic polymer; the polar solvent is a hydroxyl group-containing compound; wherein the inorganic nano-particles comprise the following constitutive elements: zinc element and oxygen element. A zinc oxide nanoparticle layer printed by the ink composition has better film-forming uniformity. 本申请提供一种墨水组合物及量子点发光二极管的制备方法。墨水组合物包括：极性溶剂，所述极性溶剂为含有羟基的化合物；无机纳米颗粒，所述无机纳米颗粒的构成元素包括锌元素和氧元素；两亲性聚合物。采用本申请中墨水组合物所打印得到的氧化锌纳米颗粒层成膜均匀性更好。
