Chalcogenide perovskite and method for producing chalcogenide perovskite by liquid phase synthesis

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.
