Abstract

Optical thermometry based on fluorescence intensity ratio of rare earth ions has attracted widespread attention due to its non-contact, fast response time, immune to interference and high sensitivity. In this study, we developed Tm³⁺/Yb³⁺ doped Ba₅Gd₈Zn₄O₂₁ phosphors for temperature sensing purposes. The structure, morphology and luminescent performances of these phosphors were comprehensively explored using X-ray diffraction, scanning electron microscopy and photoluminescence techniques. Furthermore, we explored the temperature-dependent fluorescence intensity ratio of Tm³⁺ (¹G₄ → ³H₆ and ³F₂ → ³H₆) with a temperature range of 303–573 K. Our results demonstrate excellent relative sensitivity and resolution for high-temperature sensing applications (S_R = 1.94 % K⁻¹, ΔT = 0.61 K). Overall, our findings highlight the promising potential of BGZO:Tm³⁺/Yb³⁺ phosphors in optical thermometry sensing.

基于 Tm3+/Yb3+ 共掺杂 Ba5Gd8Zn4O21 荧光粉的上转换温度计

基于稀土离子荧光强度比的光学测温因其非接触、响应速度快、抗干扰性强和灵敏度高而受到广泛关注。本研究开发了掺杂 Tm3+/Yb3+ 的 Ba5Gd8Zn4O21 荧光粉，用于温度传感。我们利用 X 射线衍射、扫描电子显微镜和光致发光技术对这些荧光粉的结构、形态和发光性能进行了全面的研究。此外，我们还探索了温度范围为 303-573 K 的 Tm3+ （1G4 → 3H6 和 3F2 → 3H6）随温度变化的荧光强度比。总之，我们的研究结果凸显了 BGZO:Tm3+/Yb3+ 荧光粉在光学测温传感方面的巨大潜力。
