Abstract
A method for preparing a ZnSe quantum dot, a ZnSe quantum dot, a ZnSe structure and a display device are provided. The method includes preparing a first zinc precursor solution, a second zinc precursor solution, a first selenium precursor solution, and a second selenium precursor solution with a lower reaction activity than the first selenium precursor solution, adding the first selenium precursor solution to the second zinc precursor solution to form an intermediate of the ZnSe quantum dot, performing the following operation at least once to form the ZnSe quantum dot: sequentially adding the first zinc precursor solution and the second selenium precursor solution to the intermediate of the ZnSe quantum dot and making the first zinc precursor solution, the second selenium precursor solution, and the intermediate of the ZnSe quantum dot react.
