Abstract
The present embodiments may provide quantum dots, a method for producing same, and an electronic device, each quantum dot comprising: a core comprising Ag, In, Ga and S; and a first shell, disposed on the core, comprising at least one Group I element, at least one Group III element, and at least one Group VI element, the molar ratio of Group III element to Group I element+Group III+VI element being 1:10 to 1:2.
Claims18
A quantum dot comprising:
- a core including silver (Ag), indium (In), gallium (Ga) and sulfur(S);
- and
- a first shell on the core, the first shell including at least one Group I element, at least one Group III element and at least one Group VI element, wherein the first shell has a molar ratio of the Group III element and the Group I element+the Group III element+the Group VI element of 1:10 to 1:2.
A method for manufacturing a quantum dot, the method comprising:
- a core preparation step of preparing a core by injecting and reacting a silver precursor, an indium precursor, a gallium precursor, a sulfur precursor and a solvent in a first reactor;
- and
- a first shell preparation step of preparing a first shell by injecting and reacting the prepared core in a first reactor containing at least one of a Group I precursor including a Group I element and a Group III precursor including a Group III element, and a Group VI precursor including a Group VI element, wherein the first shell has a molar ratio of the Group III element and the Group I element+the Group III element+the Group VI element of 1:10 to 1:2.
An electronic device comprising:
- a display device including a light emitting diode including a quantum dot;
- and
- a controller driving the display device,
- wherein the quantum dot comprising:
- a core including silver (Ag), indium (In), gallium (Ga) and sulfur(S), and a first shell on the core, the first shell including at least one Group I element, at least one Group III element and at least one Group VI element, wherein the first shell has a molar ratio of the Group III element and the Group I element+the Group III element+the Group VI element of 1:10 to 1:2.
