Abstract
Provided are core-shell particles that have high luminous efficiency and are useful as quantum dots, a method for producing the same, and a film produced using the core-shell particles. The core-shell particles of the invention are core-shell particles having a core containing a Group III element and a Group V element; and a shell covering at least a portion of the surface of the core and containing a Group II element and a Group VI element, in which the proportion of the peak intensity ratio of the Group II element with respect to the peak intensity ratio of the Group III element as measured by X-ray photoelectron spectroscopy analysis is 0.25 or higher.
