Abstract
A method for preparing a quantum dot, a quantum dot, and a display device, are provided. The method includes, providing a first precursor solution, a second 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 precursor solution to form an intermediate of the quantum dot, performing the following operation at least once to form the quantum dot: without cleaning the intermediate of the quantum dot, adding the first precursor solution and the second selenium precursor solution to the intermediate of the quantum dot, and making the first precursor solution, the second selenium precursor solution, and the intermediate of the quantum dot react.
