Abstract
A color conversion particle includes a core; and a shell that contains the core and absorbs excitation light, and emits light at the core or at an interface between the core and the shell upon receiving the irradiated excitation light. The shell is composed of a chalcogenide perovskite, and the core and the shell have band alignment that induces a Stokes shift.
