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

Abstract

Herein, a scheme of Sr2+/Ca2+ ions 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...
