Abstract
The present disclosure provides a quantum dot and a manufacturing method for the same, and a luminescent material, a light-emitting element and a display device applying the quantum dot. The quantum dot includes a core and a shell layer. The core is at least one selected from the group consisting of a XII-XV group compound semiconductor nano-crystal, a XII-XVI group compound semiconductor nano-crystal, a XIII-XV group compound semiconductor nano-crystal and a XIII-XVI group compound semiconductor nano-crystal. The core contains a cadmium element and a selenium element. The shell layer contains a zinc element and a sulfur element. The shell layer encloses the core.
