The invention discloses a preparation method of quantum dot nanospheres, the quantum dot nanospheres and application, and relates to the technical field of quantum dots. The preparation method comprises the following steps: mixing hydrophobic quantum dots, an organic non-coordination solvent and a first emulsifier solution to obtain a quantum dot micelle dispersion liquid; mixing a monomer, a ligand and a second emulsifier solution to obtain a monomer droplet dispersion liquid; and polymerizing the quantum dot micelle dispersion liquid and the monomer droplet dispersion liquid in the presence of an initiator. A ligand is added into a monomer and then polymerized with quantum dots, dynamic balance of the ligand on the surfaces of the quantum dots is achieved through the introduced ligand, high PLQY of the quantum dots is maintained, and preparation of the high-PLQY quantum dot nanospheres is achieved. 本发明公开了量子点纳米球的制备方法、量子点纳米球及应用，涉及量子点技术领域。制备方法包括：将疏水量子点、有机非配位溶剂和第一乳化剂溶液混合得到量子点胶束分散液；将单体、配体和第二乳化剂溶液混合物得到单体液滴分散液；将量子
