  "abstract": "： Temperature sensing plays a pivotal role in environmental, biomedical, and industrial applications. While most luminescence-based sensors operate in the visible spectrum, their effectiveness is limited in scenarios requiring deep tissue penetration or low background interference. Near-infrared (NIR) luminescence sensing address these limitations yet its development is hampered by low quantum yields and severe thermal quenching of rare-earthdoped materials. These limitations lead to sensing instability across broad temperature ranges, compromising their real-time monitoring capabilities in complex environments. In this work, we report a Yb3+/Nd3+ dual-emission rare-earth MOF integrated with Au nanoparticles to harness surface plasmon resonance (SPR) effects. By synergistically combining SPR-induced electromagnetic field enhancement with fluorinated ligands that effectively suppress vibrational quenching, the quantum yield was enhanced from 11.32% to 19.51%, enabling stable, high-sensitivity near-infrared temperature sensing across a wide operational window 2 / 39 covering 78-348 K. This strategy effectively addresses long-standing trade-offs between quantum efficiency and thermal stability, providing a generalizable platform for high-precision thermal sensing in biomedical and catalytic systems.",
