New phosphor exploration from single particle and local structure

Ceramics phosphors with luminescent centers are composed of luminescent center ions and host materials that accommodate these centers. In this paper, three topics for new phosphor exploration are presented. (1) new phosphor exploration focusing on individual phosphor particles within powder products for the discovery of new material phosphors, (2) new phosphor with unique luminescent centers different from the conventional substitutional type, and (3) new phosphor exploration utilizing local structure similarity to achieve desired luminescent properties.
