Abstract
The present application discloses a preparation method of a core-shell quantum dot and a core-shell quantum dot. The preparation method of the core-shell quantum dot includes the following steps: providing a silicon quantum rod; growing a cadmium-free semiconductor shell layer on a surface of the silicon quantum rod to obtain a core-shell quantum dot. The present application grows the cadmium-free semiconductor shell layer on the surface of silicon quantum rod, and the core-shell quantum dot obtained in this way includes a silicon quantum rod and a cadmium-free semiconductor shell layer coated on the surface of silicon quantum rod.
