Abstract
Provided are a core shell particle including a core which contains a Group III element and a Group V element, and a shell which covers at least a part of a surface of the core and contains a Group II element and a Group VI element, in which a ratio of a peak intensity showing a bond between the Group III element and the Group II element to a peak intensity showing a bond between the Group III element and the Group V element, which is measured by Raman spectroscopy, is in a range of 0.16 to 0.33; a method of producing the core shell particle; and a film formed of the core shell particle.

A core shell particle comprising:
- a core which contains a Group III element and a Group V element;
- and
- a shell which covers at least a part of a surface of the core and contains a Group II element and a Group VI element,
- wherein a ratio of a peak intensity showing a bond between the Group III element and the Group II element to a peak intensity showing a bond between the Group III element and the Group V element, which is measured by Raman spectroscopy, is in a range of 0.16 to 0.33.
A method of producing a core shell particle, comprising:
- a first step of mixing a Group III raw material containing a Group III element with a Group II raw material containing a Group II element such that a molar ratio of the Group II raw material to the Group III raw material is 1.5 or greater to prepare a mixed solution containing the raw materials dissolved therein;
- a second step of adding a Group V raw material containing a Group V element to the mixed solution to form a core containing the Group III element and the Group V element;
- and
- a third step of adding a Group VI raw material containing a Group VI element to the mixed solution after the formation of the core to form a shell containing the Group II element and the Group VI element in at least a part of a surface of the core,
- wherein the third step is performed at a temperature of 255° C. to 295° C.
