Annealing BaAl<sub>2</sub>O<sub>4</sub>:Tb<sup>3+</sup>/Tb<sup>4+</sup> in air and a reducing atmosphere: a strategy to enhance luminescence by eliminating Tb<sup>4+</sup>
The enhancement of green luminescence in terbium (Tb)-doped BaAl 2 O 4 phosphors was significantly influenced by the annealing environment, primarily due to the reduction of Tb 4+ to Tb 3+ – a key factor for solid-state lighting applications.
