Exploring Intrinsic Electron-Trapping Centers for Persistent Luminescence in Bi3+-Doped LiREGeO4 (RE = Y, Sc, Lu): Mechanistic Origin from First-Principles Calculations

Zheng Quo et al.

Summary: This study systematically investigated the optical transitions, formation energies, and charge-transition levels of dopants and intrinsic point defects in Bi3+-doped LiREGeO4 compounds using hybrid functional theory calculations. The results revealed that the charging process for persistent luminescence is due to D-band transition of Bi3+ and involves electrons from dopants in trapping and detrapping processes. The main electron-trapping centers identified were antisite defects Ge-Li(0), interstitial defects Li-i(0), and dopants Bi2+.
