Keywords:phosphor, machine learning, emission peak

Eu²⁺-activated phosphors exhibit various luminescence properties by different host compounds. For rapid development of new phosphors suitable for practical uses, it is necessary to design and discover host compounds that satisfy requirements from the applications, and to perform experiments efficiently. In this study, a machine learning model for emission peak tops of Eu²⁺-activated phosphors is developed for screening of host compounds from the viewpoint of emission color.
