Abstract
The present application relates to a quantum dot, a preparation method thereof, and a quantum dot film. The quantum dot of the present invention includes a quantum dot core and a metal shell, and a hollow ring is formed between an inner wall of the metal shell and an outer wall of the quantum dot core. The present invention prevents the use of a transition shell such as SiO2 in the prior art to ensure a spacing between the quantum dot core and the metal shell; prevents the ligand modification of quantum dots, thereby preventing reduction of fluorescence efficiency of the quantum dot, thus maintaining an original light conversion efficiency of the quantum dot.
