## Abstract The long‐lasting phosphorescence properties of Y~2~O~2~S:RE^3+^ (RE = Lu, Gd) phosphors and the undoped Y~2~O~2~S matrix are systematically investigated in this paper. The brightness and persistent time of the defect‐related emission around 540 nm in the undoped Y~2~O~2~S matrix are gre
