Defect compensation and intervalence charge transfer state-based Pr3+-doped niobate antithermal quenching phosphors

Defect compensation and intervalence charge transfer state-based Pr3+-doped niobate antithermal quenching phosphors

Herein, a scheme of Sr2+/Ca2+ ion substitution was employed to simultaneously regulate the defect and intervalence charge transfer (IVCT) state of Sr2−xCaxNb2O7:Pr3+ phosphors, resulting in a dual-modulation strategy for enhancing phosphor thermal stability.
