A ZnSe quantum dot, wherein a fluorescence emission peak of the ZnSe quantum dot is in a range of 455 nm to 470 nm, and a full width at half maximum of fluorescence of the ZnSe quantum dot is less than 30 nm.
A ZnSe quantum dot, wherein a fluorescence emission peak of the ZnSe quantum dot is in a range of 455 nm to 470 nm, and a particle size of the ZnSe quantum dot is in a range of 8 nm to 17 nm.
A method for preparing a ZnSe quantum dot comprising:
- 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;
- and
- 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 them react.
