文摘

•: The phosphor BaZnSiO₄: Eu²⁺/Tm²⁺/Yb²⁺ can be prepared in air.
•: The self-reduction of RE³⁺ to RE²⁺ result from the defect chemistry at Ba²⁺ sites.
•: BaZnSiO₄ can stabilize low-valence ions is due to its three-dimensional network.
•: The white-emitting phosphor BaZnSiO₄:0.03Eu show a superior synthesis route.
