Synergistic luminescence of Tb³⁺ and Pr³⁺ ions in Sr₂Y(MoO₄)₄ for high-resolution optical thermometry.

ABSTRACT: Phosphors of the SrY₂(MoO₄)₄ series co-doped with Pr³⁺ and Tb³⁺ ions were synthesized and investigated for optical temperature sensing applications. Their structure, morphology, and photoluminescent properties were thoroughly characterized using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), UV-vis absorption spectroscopy, and photoluminescence (PL) analysis. The intense dual-mode color-tunable emission revealed prominent transition bands corresponding to ⁵D₄ → ⁷F _j (j = 6, 5, 4, 3) for Tb³⁺ and ³P₀ → ³H₆ and ³P₀ → ³F₂ for Pr³⁺ ions under U
