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.

Abstract: A chalcogenide perovskite, having a crystallite size T1 of less than 40 nm, calculated by Scherrer equation based on the diffraction peak having the largest peak height in the X-ray diffraction spectrum obtained by X-ray diffraction measurement, and a proportion of a total area occupied by particles having a particle diameter of 10 μm or more measured by microscopy to a total area occupied by particles existing in a captured image range in an image range captured by a microscope of 10% or less.
