Title:
COLOR-CONVERSION PARTICLE
Document Type and Number:
WIPO Patent Application WO/2022/113984
Kind Code:
A1
Abstract:
A color-conversion particle of the present invention comprises a core and a shell that surrounds the core and absorbs excitation light. The color-conversion particle receives irradiated excitation light and causes light emission at the core or at the interface of the core and shell. The core is constituted of a chalcogenide perovskite, and the core and shell have a band alignment that expresses a Stokes shift.
