Application: Color conversion particle (Patent ID: US20240034926A1)
The patent by Idemitsu Kosan Co Ltd. describes a color conversion particle with a core and a shell made of a chalcogenide perovskite that absorbs excitation light and emits light at the core or interface upon receiving irradiated excitation light. The band alignment between the core and shell induces a Stokes shift, enhancing the efficiency of light emission.
The claims detail various aspects of the color conversion particle, including the crystal structure of the chalcogenide perovskite, chemical formulas, band alignment conditions, band gaps, shell thickness, presence of foreign substances, gradient physical properties, and the possibility of multiple layers or cores. The patent also covers the use of different chalcogenide perovskites for the core and shell, such as SrZrS3 and SrHfS3, and their applications in powders, solutions, thin films, sheets, and devices. Overall, the patent aims to protect the innovative design and composition of color conversion particles for efficient light emission in various applications.
